Final Answer:
The inequality 9c ≤ 65 can be used to find the maximum number of charms Jill can buy with $65.00. Option A is answer.
Step-by-step explanation:
Jill bought 9 charms for $40.50, so each charm costs $40.50 / 9 = $4.50. With $65.00, Jill can buy a maximum of 65.00 / 4.50 = 14.44 charms. However, Jill can only buy whole charms, so the maximum number of charms she can buy is 14.
The inequality 9c ≤ 65 can be used to represent this situation. The variable c represents the number of charms Jill can buy. The inequality 9c ≤ 65 states that the number of charms Jill buys (9c) must be less than or equal to 65. This inequality ensures that Jill does not buy more charms than she can afford.
Therefore, the inequality 9c ≤ 65 can be used to find the maximum number of charms Jill can buy with $65.00. Option A is answer.
