Question

Kari uses the equation C = 2h + 6 to find the total cost, C, in dollars, of renting a go-cart for h hours. If Kari does not spend more than $30, what is the maximum number of hours she can rent the go-cart?

Answer 1

Answer:

Maximum number of hours would be 12 hours.

Step-by-step explanation:

The inequality is 2h+6 ≤ C, where:

h = number of hours

C = total cost ($30 in this example)

"not spend more than" equates to the inequality symbol of ≤

2h+6 ≤ 30, subtract 6 from both sides

2h ≤ 24, divide both sides by 2 to isolate the variable

h ≤ 12 (i.e. 12 is the most or maximum number of hours)
