Solve Problems Using Systems of Linear Equations
-Jamil always throws loose change into a pencil holder on his desk and takes it out every two weeks. This time it is all nickels and dimes. There are 9 times as many dimes as nickels, and the value of the dimes is $\$ 10.20$ more than the value of the nickels. How many nickels and dimes does Jamil have?
A) 12 nickels and 108 dimes
B) 13 nickels and 117 dimes
C) 11 nickels and 99 dimes
D) 108 nickels and 12 dimes

Quizplus · Accepted Answer

Let the number of nickels be $n$ and the number of dimes be $d$. The problem gives us two equations: $d = 9n$ and $0.10d - 0.05n = 10.20$. Solving these equations simultaneously, we find that $n = 12$ and $d = 108$, which corresponds to choice A.
