Step-by-step explanation:
We can turn this into an equation.
Let’s denote the amount of money James makes as X.
Then Lin makes X + 3100.
Together they make 81960.
So combine their earning expressions.
X + X + 3100 = 81960
Solve for X
X = 39430
So James makes $39430 since his earnings are demoted by x.
Lin then makes 3100 + 39430, which is $42530.
