Answer:
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.
