Rochelle Corporation makes reservations for vacation homes. Rochelle Corporation provides complimentary coffee packets at a cost of $2 per guest who stay at the mountain resort. The general manager reported a total cost of $5,000 for coffee during the previous quarter. The historical number of guests at the mountain resort is 10,000 guests during the year. The manager uses the formula to compute the total variable cost (y) = Variable cost per unit of activity (v) × Volume of activity (x). The manager expects 500 guests in December. Which of the following is the correct cost equation to compute y in the cost equation for 500 guests?

y = $2 × 500

y = $8,000 + $1.75x

Which of the following equations best expresses the straight line equation for a mixed cost equation when y = total cost, v = variable cost per unit, x = volume of activity, and f = fixed cost (vertical intercept)?

y=vx+f
