2. A huge frog ate 140 big bugs in 5 days. Each day, it ate 8 more bugs than it did on the previous day. How many bugs did the frog eat on… the first day?__________________ the second fifth day> ___________

Answer 1

on the first day the frog ate 12 bugs
second day the frog ate 20 bugs
third day the frog ate 28 bugs
fourth day the frog ate 36 bugs
fifth day the frog ate 44 bugs

Answer 2

In the first day the frog ate 12 bugs.

In the second fifth (4th) day the frog ate 36 bugs.

Given data :

Total eaten in 5 days = 140

Everyday the count increases by 8.

Let,the number of bugs eaten in the first day = x

So,in the second day the number of bugs = x + 8

Third day = x+8+8 = x+16

Fourth day or second fifth day = x + 16 + 8 = x + 24

Fifth day = x+24+8 = x+32

So,

x+x+8+x+16+x+24+x+32 = 140

5x + 80 = 140

5x = 60

x = 12

So,the frog ate 12 bugs in the first day. (Answer)

In the second fifth day the frog ate = 12+24 = 36 bugs (answer)
