Answer:
you will have 70, having earned 40 in addition to the 30 you had beforehand
Answer:
y=20x+30
you will earn 40 dollars after 2 hours
Step-by-step explanation:
As you said y=money you make every hour. so y=20 then x is for every one hour. so now you have your slope equation y=20x. But then you need b (original start of money) technically your y intercept, +30. so y=20x+30. Sorry if the explination is a bit off.
