This question is a little ambiguously worded, however I assume the answer would simply be:
$500 - $112 - $28 = the amount he has left.

Answer: y = 1200m + 57,600
Step-by-step explanation: To be a line, let's say that x is the numbers of years on the job and y the salary.
So, we have (2,60000) and (7,66000)
y = mx + b
66000 = 7m + b
60000 = 2m + b (-)
________________________
6000 = 5m
m = 6000/5 = 1200
60000 = 2m + b
60000 = 2.1200 + b
60000 = 2400 + b
b = 60000 - 2400
b = 57600
y = mx + b
y = 1200m + 57,600
38% :)))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))
Your equation is gonna be
4.5a + 2.5b = 4.25
I forgot how lol but you gotta now solve for A and B.
