Answer:
James earns $39,410 a year.
Lin earns $42,910 a year.
Step-by-step explanation:
You can answer this by setting up a system of equations.
Let's say we have j, for James, and l, for Lin.
Lin earns $3,500 more than James per year. Let's put that into an equation.
j+3500= l
And, together, they earn $82,320. Let's put that into an equation too.
j+l= 82320
We can take what we got from our first equation and plug that into the second one.
j+(j+3500)= 82320
2j+3500= 82320
2j= 78820
j= 39410
Now we know that James earns $39,410 a year. All we have to do is add $3,500.
39410+3500= 42910
We'll double check by adding Lin's and James' incomes together.
42910+39410=82320
Therefore...
James earns $39,410 a year.
Lin earns $42,910 a year.
Answer:
James earn = $39410, Lin earn = $42910.
Step-by-step explanation:
Given : Lin earns $3500 more per year than James. Together they earn $82,320.
To find : How much does each of them earn per year.
Solution : We have given
Lin earns $3500 more per year than James.
According to question :
Let the James earn per year = x .
Lin earn per year = 3500 + x .
So, Together they earn $82,320.
James earning +Lin earning = $82,320.
Plugging the values.
x + 3500 + x = $82,320.
2x + 3500 = $82,320.
On subtracting both sides by 3500
2x = $82,320 -3500 .
2x = 78820
On dividng both sides by 2
x= 39410.
James earn = $39410.
Lin earn = $39410 + 3500
Lin earn = $42910.
Therefore, James earn = $39410, Lin earn = $42910.
