Answer 1

Answer: She donated $9.86.

Step-by-step explanation:

She earns $11.60 per hour.

She donates $\frac{1}{10}$ .

She worked $8\frac{1}{2}$ hours.

How much did she donate?

--------------------------------------------------------------

If she earns $11.60 per hour, how much is that in $8\frac{1}{2}$ hours?

First, let's convert the mixed number to an improper fraction. You can do this by multiplying the big number times the denominator and adding the numerator; all over the same denominator.

$8\frac{1}{2}=\frac{8*2+1}{2}=\frac{16+1}{2}=\frac{17}{2}$

Now divide to obtain a decimal number.

$17/2=8.5$

She worked 8.5 hours. Multiply this by 11.60 which is the amount she earns per hour.

8.5*11.60=$98.60

Now to calculate $\frac{1}{10}$ of $98.60, multiply again.

$\frac{1}{10}*98.60=\frac{98.60}{10}=9.860=9.86$
