Problema Solution
marissa has $4.00 in quarters and dimes. if she has 2 more quarters than dimes how many of each coin does she have
Answer provided by our tutors
let 'd' represent the number of dimes Marissa has, then 'd+2' represents the number of quarters
a dime is 0.10
a quarter is 0.25
expressed as an equation:
4.00 = 0.10d + 0.25(d+2)
-----------------
-----------------
d=10
10+2=12
Marissa has 10 dimes and 12 quarters.
