Problema Solution
Molly has $14.25 in coins. She has two more nickels than dimes. She has nine fewer quarters than dimes. How many quarters does she have?
Answer provided by our tutors
Quarter: x-9
Dime:x
Nickel:x+2
The equation is
0.25*(x-9) + 0.1x + 0.05(x+2) = 14.25
So
x = 41
So
Quarter: 32
Dime:41
Nickel:43
She has 32 quarters
