You can put this solution on YOUR website! let n = no. of nickels
let q = no. of quarters
:
Write an equation for each statement
:
"Maria has a collection of coins; the value of the collections is $7.50."
.05n + .25q = 7.50
:
" There are six more quarters than nickels."
q = (n+6)
:
Replace q in the 1st equation with (n+6), find n
.05n + .25(n+6) = 7.50
:
I think you can do this now.
