Question

ashton services the vending machines at a car wash. customers pay $3 per air freshener. ashton restocks the product and collects the money. he adds 34 air fresheners to fill the machine and collects $63. why might ashton be concerned that the machine is not working correctly?
a) he is not sure how many air fresheners customers purchased.
b) his estimate for how much money the machine should have is much higher than what he collected.
c) his estimate for how much money the machine should have is much lower than what he collected.
d) he does not know the total number of air fresheners the machine holds.

Explanation:

First, calculate the expected revenue from 34 air fresheners: \( 34 \times 3 = 102 \). The collected amount is $63, which is less than $102. Option C states his estimate (expected) for the machine's money is higher than collected, matching the concern about the machine not working. Option A is about quantity of air fresheners sold, not money discrepancy. Option B says estimate is higher than collected (opposite of correct). Option D is about total capacity, irrelevant. So C is correct.

Answer:

C) His estimate for how much money the machine should have is much higher than what he collected.
