Question

In three days Speedy the squirrel ate 30 peanuts. On both the second and third day, Speedy ate 7 peanuts more than on the day before. How many peanuts did Speedy eat the first day?

Answer 1

3 peanuts

Explanation:

x represents peanuts eaten on first day

30 peanuts eaten in 3 days

7 more peanuts eaten every day after first day which gives the equation:

x+(x+7)+(x+14) = 30

3x+21 = 30

3x = 9

x=3
