Question

Phineas has $1.15 worth of change in his pocket. He has three more dimes than quarters and two more dimes than nickels. How many of each type of coin has he~

Answer 1

let x = number of quarters

let x + 3 = number of dimes

let x + 3 - 2 = number of nickels (he has more dimes than nickels, so we have to subtract 2)

.25x + .10(x+3) + .05(x + 1) = 1.15

.25x + .10x + .30 + .05x + .05 = 1.15

.40x + .35 = 1.15

.40x = .80

x = 2

He has 2 quarters, 5 dimes, and 3 nickels. I hope this helps! Please let me know if you have any questions.
