Lester worked 12 hours last week at the grocery store and earned $93.00. If
he continues to earn the same hourly pay, how many additional hours must
he work to earn another $62.00?

4+4+2x

or

2x+8

step-by-step explanation:

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
