Question

A local car company was able to make 12 cars a week for

4 weeks. They doubled this amount over the next 4
weeks. How many cars did they make after the 8 weeks?

Answer 1

144

Explanation:

for the first 4 weeks:

In the first four weeks they made 12 cars per week. So in total they made 48 cars since they made 12 cars four times in that period and 4x12=48

for the next 4 weeks:

In the next four weeks they doubled the amount of cars so they made 24 cars a week for four weeks since 12x2=24. So for this time period they made 96 cars since 24x4=96.

for the total 8 weeks:

If we add the two time period of 4 weeks together we get 8 weeks since 4+4=8. That means we just add the two totals of cars together. 96+48=144.
