Answer 1

Answer:

60

Step-by-step explanation:

Let's say T is the number of magazines sold by Terrance, and L is the number of magazines sold by Lee.

Terrance sold 30% more than Lee plus 12.

T = 1.3L + 12

Overall, Terrance sold 50% more than Lee.

T = 1.5L

Setting the expressions equal:

1.3L + 12 = 1.5L

12 = 0.2L

L = 60

Lee sold 60 magazines.
