3(10x) + 5x +5(25x)-20x=3600
x=25
1 quarter

anonymous · Answer

i am not sure about the answer though

anonymous · Answer

Wouldn't it be 10(x + 3)...etc, cause it says 3 MORE dimes than nickels not sure to add or multiply

anonymous · Answer

Let x=amount of nickles
Then amount of dimes=(x+3)
And amount of quarters=(2x-5)
We then have 5(x)+10(x+3)+25(2x-5)=360
Solve: 65x=455
x=7 (we have seven nickles)
So we have 9 (2*7-5) = 9 quarters
