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 Jamil have x nickels.
Number of dimes=y.
So, y=2x
0.05x=0.1y+1.65(Multiply Both sides by 2)
0.1x+3.30=0.2y(Plug y=2x from first equation.)
0.1x+3.30=0.4x
0.3x=3.30
x=11
Number of nickel=11 and number dimes=2*11=22
