Dedra bought 10 more jelly donuts than chocolate donuts. She bought 6 times as many jelly donuts as chocolate donuts. How many chocolate donuts did Dedra buy?

Solution:

Dedra bought j jelly donuts

So

j =(c+10)

j=6c

therefore

6c=c+10

5c=10

c=10/5=2

So Dedra bought 2 chocolate donuts and 12 jelly donuts
