Question

Waldo ate a total of 100 peanuts over a period of 5 days. Each day he ate six more peanuts than on the previous day.

How many peanuts did he eat on the first day?

Answer 1

1st day = x

2nd day = x+6

3rd = x+6+6

4th = x+6+6+6

5th = x+6+6+6+6

5x+60 = 100

5x = 40

x = 8 (1st day)

Step-by-step explanation:

He ate 8 peanuts on the first day.
