In my question for math it said write a coin problem that has an answer of 21 quarters and 24 dimes.
Then I have to write a system of equations for it.
:
We know there are a total of 45 coins, write a total coin equation
q + n = 45
:
Find the total value and make a equation from that
21(.25) + 24(.10) = $7.65
:
.25q + .10d = $7.65; the total value equation
