Question

A youth organization collected nickels and dimes for a charity drive. By the end of the 1-day drive, the youth had collected $60.5060.50. If there were five times as many dimes as nickels, how many of each type of coin was collected?

Answer 1

d = 5n (Think about it, it's backward from what seems right.)

5n + 10d = 6050 (everything multiplied by 100)

 

Now substitute.

 

5n + 10(5n) = 6050

55n = 6050

n = 110

 

d = 5(110) = 550

 

Hope this helps!
