Question

Tanya and Keisha volunteer at the hospital after school. A local company has promised to donate one quarter to the hospital for every hour a student volunteers during the year. By the end of the year, Tanya and Keisha together have earned $58.50 for the hospital. Keisha volunteered twice as many hours as Tanya.

Answer 1

I hope this helps you!

Answer 2

Let's divide 58.50 by .25 to find out how many hours both worked in total...

so we have 234 hrs And Keisha worked 2/3 of them and Tanya worked 1/3 of them

So 2/3 of 234 = 156 and 1/3 of 234 = 78
