If Sarah has a total of 37 nickels and dimes on her desk, and they have a combined value of , how many of each coin does he have? Set up a system of linear equation to solve this problem. Let n represents nickels and d represent dimes.

Write an equation about the number of nickels and dimes_______________________

Write an equation about the total value of the coins___________________________

Sarah has__________nickels and_________dimes

Answer 1

N+ D = 37

.05N + .10D = 3.00

.05N +.05D = .05(37) = 1.85

subtract to get

.05D = 3.00-1.85

D = 1.15/.05 = 23 Dimes

N= 37-23 = 14 Nickels

.05(14) + (.10)23 = .7 + 2.3 = 3.00
