Question

Which inequality could Teresa use to determine the cost of each tire?

a) (2x leq 120 + 25)
b) (2x geq 120 - 25)
c) (2x = 120 + 25)
d) (2x leq 120 - 25)

Answer 1

Teresa can determine the cost of each tire by using the inequality 2x ≤ 120 + 25.

Step-by-step explanation:

To determine the cost of each tire, Teresa can use the inequality symbol to show the relationship between the cost of each tire and the number of tires. Since the inequality symbol represents how two metric measurements are related, a suitable inequality to use in this scenario could be:

2x ≤ 120 + 25

This inequality states that twice the number of tires (2x) should be less than or equal to the sum of $120 and $25. This means that the cost of each tire multiplied by 2 should be less than or equal to $145. Teresa could solve this inequality to determine the maximum cost of each tire.
