Question

James and Lin got married and got new jobs. Lin earns $3100 more per year than James. Together they earn $81,980. How much does each of them earn per year?

Answer 1

The earning to James per year is $ 39,440

The earning of Lin per year is $ 42,540 .

Explanation:

Given as :

The total earning of James and Lin together = $ 81,980 per year

The earning of Lin is $ 3100 more per year than James

Let The earning of James = $ J

And The earning of Lin = $ J + $ 3100

So, According to question

The total earning of James and Lin together = $ 81,980 per year

Or, The earning of Lin + The earning of James = $ 81,980 per year

Or, $ J + $ 3100 + $ J = $ 81,980 per year

or, 2 $ J = $ 81,980 - $ 3100

Or, 2 $ J = $ 78880

∴ J =
`(78880)/(2)`

I.e The earning to James per year = $ 39,440

And The earning of Lin per year = $ 34,440 + $ 3100 = $ 42,540

Hence, The earning to James per year is $ 39,440

And The earning of Lin per year is $ 42,540 . answer
