Answer:
Dog ate 6 biscuits on first Day
Step-by-step explanation:
Complete Question :
A dog eat 80 biscuits in 5 days. Assume that Each day it ate 5 biscuits more than the day before. How many biscuits did he eat on the first day?
Let say on First Day he ate = A biscuits
He ate next day A + 5
then 3rd day A + 5+ 5 = A + 10
Then 4th day A + 15
5th Day = A + 20
Total biscuits ate = A + A +5 + A + 10 + A + 15 + A + 20 = 5A + 50
5A + 50 = 80
=> 5A = 30
=> A = 6
