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)

-----------------

solve for the number of dimes

-----------------

d=10


10+2=12


Marissa has 10 dimes and 12 quarters.
