Question

Adita earns $9.40 per hour working at an animal shelter. How much money will she earn for 18.5 hours of work?

Answer 1

`x=$173.9`

Explanation:

Thinking about proportion can help here. First, let call X how much she earns.
So, Adita earns `$9.40 = 1hr`
then, `x=18.5hrs` Since these are proportional and equal to hours we could set them into a fraction that money earns equal to hours worked.
Hence;
`($9.40)/x=(1hr)/(18.5hrs)` to remove the denominators, we will multiply both sides of the equation by the denominators(cross multiply)
`x*(($9.40)/x)*18.5hrs=18.5hrs((1hr)/(18.5hrs))*x`
`$173.9hrs=x(hr)` find x, x is how much she earns.
`x=$173.9`
