Breanna has quarters, dimes, and nickels in her purse. she has 3 fewer nickles than dimes, but she has 2 more nickles than quarters. if brianna has 2 quarters how much more money does she have?

We base ourselves in the one piece of crucial evidence: She has 2 quarters.
-from the rest of the problem, we know that she has 2 more NICKEL'S than QUARTERS, 

(2 Quarters + 2 = 4 nickels)

she has 3 fewer nickels than dimes, 

DIME - 3 = Nickels

D - 3 = 4

D = 7

7 dimes
(70 cents)

4 nickels
(20 cents)

2 quarters
(25 cents)

115 cents
or $1.15
