Tina is sorting out her magazines. She arranges them into 9 piles of 4 and 5 piles of 8. How many magazines does Tina have in all?
A) 85 magazines
B) 76 magazines (Correct Answer)
C) 26 magazines
Explanation:
This problem can be solved in two steps. The first step is to multiply 9 by 4 and 5 by 8. The two products are 36 (9 x 4 = 36) and 40 (5 x 8 = 40). The second step is to sum these two products. The sum of 36 and 40 is 76. Tina has 76 magazines in all.
