3 days

Worker checked 2,950 products in 3 days. Second day checked 25% more than the first day. The third day 15% more products than the second day. How many products he checked in each day.

Correct answer:

a =  800
b =  1000
c =  1150

Step-by-step explanation:


a+b+c=2950
b = 1.25 a
c = 1.15 b

a+b+c=2950
b = 1.25•a
c = 1.15•b

a+b+c = 2950
1.25a-b = 0
1.15b-c = 0

a = 800
b = 1000
c = 1150
