Question

Nina has been given the formula to figure out her weekly salary I = 0.88( 9h + 0.12s). The hours that Nina works per week is represented by h, while s represents the monetary value of the sales that Nina makes per week. Which of the following represent the monetary value of the sales that Nina makes in any given week? Select all that apply.

Answer 1

Answer:

$s=\frac{I-7.92h}{0.1056}$  or  $s=\frac{I}{0.1056}-75h$

Step-by-step explanation:

we have

$I=0.88(9h+0.12s)$

Solve for s

That means -----> Isolate the variable s

Distribute right side

$I=7.92h+0.1056s$

Subtract 7.92h both sides

$I-7.92h=0.1056s$

Divide by 0.1056 both sides

$\frac{I-7.92h}{0.1056}=s$

Rewrite

$s=\frac{I-7.92h}{0.1056}$

Simplify

$s=\frac{I}{0.1056}-\frac{7.92h}{0.1056}$

$s=\frac{I}{0.1056}-75h$
