Answer 1

Answer: She donated $9.86.

Explanation:

She earns $11.60 per hour.

She donates
`(1)/(10)` .

She worked
`8(1)/(2)` hours.

How much did she donate?

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

If she earns $11.60 per hour, how much is that in
`8(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(1)/(2)=(8*2+1)/(2)=(16+1)/(2)=(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
`(1)/(10)` of $98.60, multiply again.

`(1)/(10)*98.60=(98.60)/(10)=9.860=9.86`
