PROBLEM:
I spent $141.00 at the bakery buying bread rolls for 60c and 85c. How many of each roll did I buy?

Thank you!

You would have bought

65 rolls of 60c = $39
120 rolls of 85c = $102

So $39 + $102 = $141

You probably need to know the total number of rolls, because otherwise the answer could be 235 rolls for 60¢

Did you really buy 210 bread rolls?
That's alot of bread.

150 60c rolls
60 85c rolls
