Question

Marko has 45 comic books in his collection, and Tamara has 61 comic books. Marko buys 4 new comic books each month and Tamara buys 2 comic books every month. After how many months will Marko and Tamara have the same number of comic books?

Answer 1

After 8 month

Explanation:

4x + 45 = 2x + 61

4x - 2x = 61 - 45

2x = 16

x = 16/2

x = 8

Mario: (4*8) + 45 = 77 comic books

Tamara: (2*8) + 61 = 77 comic books
