X ·2 = 12x - 15

2x = 12x - 15

2x + (-12x) = (12x - 15) + (-12x)

Brrunno [24]

Answer:

$41\ hours$

Step-by-step explanation:

we know that

Using proportion

$\frac{1}{800,500}\frac{hour}{kw}=\frac{x}{32,725,550}\frac{hours}{kw}\\ \\x=32,725,550/800,500\\ \\x=40.88\ hours$

Round to the nearest whole number

$40.88\ hours=41\ hours$
