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
Bumek [7]

Answer:

The earning to James per year is $ 39,440

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

Step-by-step 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 = \frac{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

A upermarket owners cost for a 26 ounce can of coffee is 6.75. A case of coffee contains 12 cans. What profit is earned for each
VladimirAG [237]

Answer:

The correct answer is 32.88.

Step-by-step explanation:

Cost price for a 26 ounce can of coffee = 6.75.

A case of coffee contains 12 cans.

Total profit for selling a case of cnas of coffee is given by 113.88 - 81 = 32.88

Thus the profit for selling each can is 32.88.
