Astore has two brands of pencils on sale for the day. brand a comes in packs of 4, and brand b comes in packs of 10. if an equal number of each brand sold, what is the minimum number of each sold?

20 Packs of each

Step-by-step explanation:

Okay, so first you add 4 until you get an answer that 10 can also equal

4+4 = 8

8+4 = 12

12 + 4 = 16

16 + 4 = 20

Okay, now for the 10

10 + 10 = 20

So, as you can see, the minimum for each is 20.

what i would say the best answer is a. 40.5
