1 quarter = $0.25
1 dime = $0.10
------------------
Set up:
Let A = number of quarters
Let B = number of dimes
Equation 1:
Equation 2:
-----------------------
Solution:
Since equation one is solved for B, Plug (3A + 11) into equation 2 for B.
Equation 2:

Multiply the 0.10 trhough.

Combine like terms.

Subtract 1.1 from both sides.

Divide both sides by 0.55

Now plug 7 into equation 1 for A.
Equation 1:

Annie has 32 dimes.
