Question

During the months of August and September the total rainfall I August was 0.6 inch more than the amount f rainfall in September, how much rain fell in each month?

Answer 1

August = 3.4

September = 2.8

Explanation:

Given

`Total = 6.2\ in`

Represent August with A and September with S.

So,

`A =S + 0.6`

Required

Amount of rainfall in each month.

This is calculated using:

`Total = August + September`

`6.2= A + S`

Recall that: A = S + 0.6. Substitute

`6.2= S + 0.6 + S`

`6.2= 2S + 0.6`

Collect Like Terms

`2S = 6.2 - 0.6`

`2S =5.6`

Solve for S

`S = 5.6/2`

`S = 2.8`

Substitute 2.8 for S in
`A =S + 0.6`

`A = 2.8 + 0.6`

`A = 3.4`
