Answer:
a)After 6 days region D will catch region C
b) Region C will sell 13500 cookies and region D will sell 13600 cookies
Step-by-step explanation:
a) Cookies sold by region C more than region D= 1500-1200=300
But region D can sells 50 cookies every day i-e
50 cookies = 1 day
==> 1 cookie= 1÷50
==> 300cookies = 300÷50=6 days
So, after 6 days region D will catch up region C's
b) If sale stopped after 8 days;
Then sale of region C for 8 days = 1500×8=12000 cookies
so , total cookies sold = 1500 +12000=13500
For region D;
Before catching up region C cookies sold by region D = 1200
Till catching up region C - region D had also sold 1500 cookies,
and for 50 extra cookies than region C
next 8 days region D will sale =(1500+50)×8=1550×8=12400 cookies
So, total number of cookies sold by region D = 1200+12400=13600
