Question

Sally gave her brother $3.95 in quarters and dimes. If the number of quarters is 6 more than the number of dimes, how many quarters did Sally give her brother?



Sally gave her brother quarters

Answer 1

just the answer please or something close

Answer 2

well let quarters be x and dimes be y. since there is 6 more quarters... y+6=x... y dimes are worth 0.1dy
x quarters are worth 0.25x

The problem states:
"$3.95 in quarters and dimes"
That means 0.1d + 0.25q = 3.95
That is our second equation.




Here are the two equations:
q = d + 6
0.1d + 0.25q = 3.95

Answer 3

sorry I changed x to q and y to d to make more sense
