Answer:
n = nickels, q = quarters
Equation 1: n+q=30
Equation 2: 0.05n+0.25q = 3.30
Step-by-step explanation:
From equation 1, n = 30-q
Substitute in Equation 2:
0.05(30-q) + 0.25q = 3.30
1.5 - 0.05q + 0.25q = 3.30
0.2q = 1.8
q = 9
Substitute in new equation:
n = 30-9
n = 21
It is important to note a nickel is worth 5 cents and a quarter is 25 cents. This helps us build the equations.

Answer:
<em>coefficient</em><em> </em><em> </em><em>because</em><em> </em><em>they</em><em> </em><em>are</em><em> </em><em>not</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>so</em><em> </em><em>they</em><em> </em><em>can</em><em> </em><em>not</em><em> </em><em>be</em><em> </em><em>constant</em><em> </em><em>because</em><em> </em><em>it</em><em> </em><em>is</em><em> </em><em>not</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>in</em><em> </em><em>every</em><em> </em><em>week</em>
c = amount of chocolate donuts
m = amount of maple donuts.
so we know the total in all is 41 donuts, thus c + m = 41.
we also know that whatever c is, m is 25 fewer than that, m = c - 25.
