Answer:
There are 27 quarters and 14 nickles
Step-by-step explanation:
<u>Step 1: Make a system of equations</u>
<em>n + q = 41</em>
<em>0.05n + 0.25q = 7.45</em>
<u>Step 2: Solve for n in the first equation</u>
<em>n + q - q = 41 - q</em>
<em>n = 41 - q</em>
<u>Step 3: Plug in n into the second equation</u>
0.05(41 - q) + 0.25q = 7.45
2.05 - 0.05q + 0.25q - 2.05 = 7.45 - 2.05
0.2q / 0.2 = 5.4 / 0.2
<em>q = 27</em>

<u>Step 4: Find the amount of nickels</u>
n = 41 - 27
<em>n = 14</em>
