Hey there, you did not finish the question.
Margo has 3 dimes. Justin has 5 dimes. *they put their money into a donation box for a local pet shelter what is the value of the money they added to the donation box
Explanation:
1 dime=10 cents
3 dimes x 5 dimes =80 cents
Your answer is $0.80
This is how algebra works, instead of saying 3 dimes x 5 dimes, you just replace it with a letter.
