The pizza shop offers a 15 percent discount for veterans and senior citizens. If the price of a pizza is $12, how would you find the discounted price?

You can subtract the discount percent from 100% and then multiply that by the original price.

Use the diagram to help you solve this problem. The pizza shop also sells artwork by local artists. For each piece it sells, the shop receives a 15 percent commission. This amount is subtracted from the price of the artwork, and the remaining amount is given to the artist. If a piece of art sells for $30, how much will the artist receive?

The pizza shop sells artwork by local artists. For each piece it sells, the shop receives a 15 percent commission. The most expensive piece it ever sold was priced at $225. Which expressions represent how much the shop received? Check all that apply. (225)(1.15) (225)(0.15) (225)(0.85) 225 - [(225)(0.15)] 225 - [(225)(0.85)]

Mindy, a local artist, sells a piece of art at the pizza shop for $15, and the shop takes 15 percent commission. Instead of receiving money, Mindy would like a $12 pizza, including 5 percent sales tax. Is this a fair trade? Explain how to find the solution.

It is a fair trade, because 85% of $15 is $12.75, and the pizza with sales tax is $12.60.

For dinner, Abelita chooses the Italian salad that costs $3.99 before tax, and Franco chooses the fettuccini alfredo that costs $7.17 before tax. If the sales tax is 5 percent, explain how to find the total cost for their dinner.

The total cost of the dinner is found by adding the two prices together. Then this sum is multiplied by 1.05, which is 100% + 5%, to get a cost of $11.72.
