1 answer:
<em><u>Lee sold 40 magazines</u></em>
Step-by-step explanation:
Equation Model:
Let m be the number of magazines Lee sold.

Let me show another way: In the image above 20% is equal to 8 so if we use 8 and 20% and try to reach our way up to 100% (How much Lee sold in total) then we will get our answer.

60%=24
80%=32
100%=40
Therefore Lee sold 40 magazines.
