Question

Francisco needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 5 hours and charged him $176 for parts. The total was $651. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.

Answer 1

x=95

Explanation:

The equation to solve this would be 651=176+5x. The first step would to subtract 176 on both sides of the equation. 651-176=176-176+5x. That equals 475=5x. Now, to isolate the variable, divide both sides of the equation by 5. 475/5=5x/5 That gives you 95=x. The cost of labor per hour is $95.

Answer 2

176 + 5x = 651

Explanation:

the parts are 176, the guy works for 5 hours and the total is 651. the hourly cost is the unknown so 176 + 5x = 651.
