Problema Solution
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 2 times as many dimes as nickels, and the value of the dimes is $1.65 more than the value of the nickels. How many nickels and dimes does Jamil have?
Answer provided by our tutors
let 'x' represent the number of nickels, then '2x' represents the number of dimes
value of the dimes is $1.65 more than the value of the nickels:
0.10*2x = 0.05x + 1.65
solving for 'x' we have x=11
2*11 = 22
there are 11 nickels and 22 dimes
