Problema Solution
Ace has $3.15 in nickels and dimes. He has 15 more nickels than dimes. How many of each type of coin does he have?
Answer provided by our tutors
let 'd' represent the number of dimes, then 'd+15' represents the number of nickels
express the equation in terms of dimes ('d') and solve:
3.15 = 0.10d + 0.05(d+15)
---------------------
---------------------
d=16
16+15 = 31
Ace has 16 dimes and 31 nickels
