Answer 1

Alternative B - $22,500

Explanation:

We can use proportion to solve this problem. In proportion we know that two ratios are equal:

We know that for each $16 you make, you spend 9. So, for each $40,000 you spend x:

16 - 9

40,000 - x

`\begin{gathered} (16)/(40000)=(9)/(x) \\ 16x=9\cdot40,000 \\ 16x=360,000 \\ x=(360,000)/(16) \\ x=22,500 \end{gathered}`

Answer: Alternative B - $22,500
