Question

I need the answer ASAP

Answer 1

16 postcards

Explanation:

So Dean's rate of buying is:

8 postcards/2 days = 4 postcards per day.

Thus, we can find out how many postcards he gets after 4 days by multiplying

4 postcards × 4 days, which equals to 16 postcards.

Hope this is helpful!

Answer 2

16

Explanation:

Since Dean bought 8 postcards during 2 days of vacation, then after 4 days, that would be 16 because multiply by 2.
