Question 4748: Please put this question into an equation that I can understand. Jenny has 175 coins in a jar. They consist of nickels and dimes only.The total value of the coins is $11.90. How many nickels and dimes are there in Jenny's jar? Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! Let N = # of nickels. A nickel = $0.05
Let D = # of dimes. A dime = $0.10
The # of nickels plus the # of dimes = 175 (The total number of coins)
N($0.05) + D($0.10) = $11.90 (The total value of the coins)
The equations you need are:
N + D = 175
N($0.05) + D($0.10) = $11.90
Solve this system of equations for N and D and you will have solved the problem.
I got: N = 112 and D = 63
