Question

At a store, each avocado costs $0.65. Which inequality represents the number of avocados, n, a customer can buy with $10.00?

A
0.65n ≥ 10
B
10n ≤ 0.65
C
0.65n ≤ 10
D
10n ≥ 0.65

Answer 1

C

Reason: total cost = $0.65·n must be less than or equal to the $10 budget, so 0.65n ≤ 10. (Thus n ≤ 10/0.65 ≈ 15.38, so at most 15 whole avocados.)
