A Farmer has 240 acres under cultivation at the cost $188.99 per acre. If he averages a yield of 60 bushel per acre, what profit is expected if the price per bushel is $5.67

First figure out total cost cultivation. $189.99 per acre x 240 acres = $45,357.60 So basically it costs the farmer $45,357.60 to maintain 240 acres. Next, figure out how much he earns per bushel. 60 bushels per acre x 240 acres- 14,400 bushel total. 14,400 x $5.67 (cost per bushel) = $81,648 $81,648 is how much he earns, but you have to subtract $45,357.60 because that's how much he is losing (spending) to maintain his farm $81,648- $45,357.60 = $36,290.40

Two workers can finish building a play set in 18 hours. How long will it take 4 workers to build 3 play sets?

If 2 workers can finish a play set in 18 hours, it would take half the time, or 9 hours, to finish the play set with 4 workers. It would then take 93 hours to finish building 3 play sets: 9 hours3play sets=27hours.

Jessie can answer multiplication problems at a rate of 6 problems every 20 seconds. If she has a 10-minute test with 175 questions on it, will she finish in time?

If Jessie can answer 6 questions in 20 seconds, and there are 60 seconds in a minute, she can answer 36=18 questions each minute. Since the test is 10 minutes long, she can answer 1018=180 questions. therefore, she will finish the 175-question test and could even complete 5 more

Mike decided to renew the paint of the kitchen and the living room. To paint the kitchen, he spends can of paint less than for the living room. If he spends can of paint for the living room, then how much did he spend for the kitchen?

If Mike spend can of paint for the living room and can of paint less for the kitchen than for the living room, then he spends: 3 4 − 2 5 55 can of paint for the kitchen. Notice that we have the difference of two fractions with different denominators. Step 2. Find the least common denominator. We need to list multiples of 4 and 5: 4, 8, 12, 16, 20, . .. 5, 10, 15, 20, 25, . .. We can see from above two lists that the least common multiple of 4 and 5 is 20. So, the least common denominator of two fractions and is 20. Step 3. Convert and into their equivalent simple fractions with the common denominator equal to 20 and calculate their difference: 3 4 − 2 5 = 5 5 ⋅ 3 4 − 4 4 ⋅ 2 5 = 15 20 − 8 20 = 7/20 Answer.

If Randy sells 8 times as many vacuum cleaners as Janice, and Janice sells 690 vacuum cleaners per year, on average, how many does Randy sell each month?

A baker can bake 4 cakes with 10 cups of sugar. If he has a 30 cup bag that is 1/2 full, how many cakes can he bake?

If the 30c bag of sugar is 1/2 full, there are 15c left. If the baker can bake 4 cakes with 10 c, he can bake 2 with 5. therefore, he can bake 2*3=6cakes

A baker can bake 4 cakes with 10 cups of sugar. If he has a 30c bag that is 1/2 full, how many cakes bake?

If the 30c bag of sugar is 1/2 full, there are 15c left. If the baker can bake 4 cakes with 10 c, he can bake 2 with 5. therefore, he can bake 2*3=6cakes

two buildings in downtown Chicago stand across the river from each other. The first buildings height is 1,700ft and it casts a shadow that is 525ft long. If the second building's height is 1,450 feet, how long will its shadow be at the same time of the day (round to the nearest foot0?

If the height of the first building is 1,700ft while its shadow is 525ft, and the second building's height is 1,450ft tall, it sets up this proportion: 1,700/525=1,450/x. By cross multiplying and solving for x we find: 1,700x=761,250; x=448ft long,

A runner leaves his house at 7:45 for a morning run. If he travels at an average speed of 6 mph and gets back home at 10:00, how many miles did he run?

If the runner is out from 7:45 to 10:00, he ran for 2:15. 2;15= 2.25 hours. Since he travels at an average of 6mph, his total travel distance is 2.25*6= 13.5 miles.

Train A leaves the station at 1:45 traveling at a constant speed of 65 mph. If it arrives at its destination at 3:15, how many miles did it travel?

If the train leaves at 1:45 and arrives at 3:15 it has been traveling for 1.5 hours. to find how far it has traveled, we multiply by the speed: 1.5*65=97.5

A bookstore has 50% more fantasy books than biographies. What is the ratio of fantasy books to biographies?

Then: 0.69 = A% ^_ 6.95 = A 100 ⋅ 6.95 Solve for A: 100 6.95 ⋅ 0.69 = 100 6.95 ⋅ A 100 ⋅ 6.95 10 ≈ A Answer. The right answer is $. 10%

In a certain class, the ratio of passing grades to failing grades is 8: 4. How many of the 36 students passed the course?

Solution. The given ratio of passing grades to failing grades tells us that for each 8 students in the class who passed the exam, there are 4 other students who failed the class. Notice that that we can write 36 = 12 + 12 + 12 = '8 + 4) + '8 + 4) + '8 + 4) = '8 + 8 + 8) + '4 + 4 + 4) = 24 + 12 So, the number of students who passed the course is 8 + 8 + 8 = 24. Answer. The right answer is E. 24

The price for bananas was 75 cents per pound over last month. Today, we see that it's been marked up to 81 cents per pound. What is the increase in percent?

The increase of price for bananas in cents per pound is: 81 − 75 = 6 Let the increase in percent be A. Then: 6 = A% ^_ 75 = A 100 ⋅ 75 Solve for A: 100 75 ⋅ 6 = 100 75 ⋅ A 100 ⋅ 75 8 = A Answer. The right answer is E. 8%
