Question

A fair rents a thrill ride for $3000. It cost $4 to purchase a token for the ride. Write and solve an inequality to determine the number of rides tokens that can be sold for the fair to make a profit of at least $750. Big Ideas Math is saying that x greater than or equal to 937.5 is wrong.

Answer 1

938

Explanation:

Given that :

Amount spent by fair on thrill. Ride = $3000

Cost per token of thrill ride = $4

For the fair to make a profit of atleast $750

Then it must realize : (cost of thrill ride + $750) = ($3000 + $750) = $3750

Therefore ;

Cost per token * number of rise tokens ≥ $3750

Let number of ride tokens = x

4x ≥ 3750

4x/4 ≥ 3750/4

x ≥ 937.5

Hence, number of tokens that must be sold = 938
