Avery need a total of $12.75 in quarters at the laundromat. She has already saved $3.25. Which equation and solution process can be use to determine, q, the number of additional quarters Avery needs to wash her laundry?

a)

$12.75=\frac{q}{25}+3.25$
Subtract 3.25 from both sides and multiply the difference by 25.

b)

$3.25-0.25q=12.75$
Subtract 3.25 from both sides and divide the difference by -0.25.

c)

$12.75=0.25q+3.25$
Subtract 3.25 from both sides and divide the difference by 0.25.

d)

$25q+3.25=12.75$
Subtract 3.25 from both sides and divide the difference by 25.
