You have a total of 45 dimes and quarters. you have 3 more quarters than dimes. which system of equations can you use to find the number x of quarters and number y of dimes you have? use the system to determine how much money you have in quarters and dimes.

$8.10

Step-by-step explanation:

Let d and q represent the # of dimes and quarters, respectively.  Then write equations reflecting this story:

q = d + 3, and d + q = 45.  Substitute d + 3 for q in the second equation, obtaining:

d + d + 3 = 45, or 2d = 42, or d = 21.  Then there are 21 dimes and 24 quarters.  That comes to $2.10 + $6.00, or $8.10.

it would be:
