Question

Noah manages a buffet at a local restaurant. he charges $10 for the buffet. on average, 16 customers choose the buffet as their meal every hour. after surveying several customers, noah has determined that for every $1 increase in the cost of the buffet, the average number of customers who select the buffet will decrease by 2 per hour. the restaurant owner wants the buffet to maintain a minimum revenue of $130 per hour.

write two expressions for this situation, one representing the cost per customer and the other representing the average number of customers. assume that x represents the number of $1 increases in the cost of the buffet.

type the cost expression on the first line and the customer expression on the second line.

Answer 1

Answer: Cost per customer expression:

10 + x

An average number of customers' expression:

16 - 2x

Note that the cost per customer expression represents the original cost of the buffet ($10) plus the additional cost for each $1 increase (x). The average number of customers expression represents the original number of customers (16) minus the decrease in customers for each $1 increase (2x).
