Answer 1

After 2 hours of work

Answer 2

Answer:

Step-by-step explanation:

X=hour

Equation for A: 100x+500

B: 50x+600

y=100x+500; you would subtract 100x from both sides and then you would subtract 50x from both sides

y-100x=500

y-50x=600  ; now you want to see where they intersect, you want isolate one of the variables so, lets get rid of y because it's easier, subtract y-y and they cancel out, now you will subtract -100x - 50x =-150x and subtract 500-600

now you have -150x=-100 now isolate x and do this by dividing -150 from both sides you should get 0.67 now you plug this x value into one of the equation and you should get the point where they intersect, correct me if I'm wrong
