Question 1142031: Martha has 2 more dimes than quarters. If she has $3.35 altogether, how many of each coin does she have? Found 2 solutions by VFBundy, greenestamps:Answer by VFBundy(438) (Show Source):
You can put this solution on YOUR website! # of quarters = x
# of dimes = x + 2
0.25x + 0.10(x + 2) = 3.35
0.25x + 0.10x + 0.20 = 3.35
0.35x + 0.20 = 3.35
0.35x = 3.15
x = 9
# of quarters = x = 9
# of dimes = x + 2 = 11
Check it:
"Martha has 2 more dimes than quarters." 9 quarters and 11 dimes...so it checks.
"If she has $3.35 altogether..." 9 quarters @ $0.25 each equals $2.25 and 11 dimes @ $0.10 each equals $1.10. $2.25 plus $1.10 equals $3.35...so it checks.
