Question

Mel wants to buy a pair of shoes that costs $120. She has saved $45 and has a job that pays her $10 per hour. The number of hours she has to work to have enough to buy the shoes is given by the inequality 10x + 45 > 120, where x is the number of hours she works. The fewest number of hours she has to work to buy the shoes is

Answer 1

Step-by-step explanation:

The solution for the inequality is x = (7.5,00).

Mel needs to work more than 7.5 hours to buy a pair of shoes that costs $120.

Step-by-step explanation:

10x + 45 > 120 //substract 45 in both sides of the inequality.

10x + 45 - 45 > 120 - 45

10x > 75

(10/10)x > 75/10 //divide by 10 both sides of the inequality

x> 7.5
