Luke earns $50 for doing his chores each month. He washes cars in his neighborhood for $15 each. Last month he earned a total of
$110. How many cars did he wash? 1. Define your variable, what is unknown?
2. Write an Equation that represents the situation.
3. Solve for the number of cars.
4. Why wouldn’t it make sense to start the table a graph to represent this at (-1,-1)
1. The variable that was unknown x amount of cars washed.
2.The equation I used was 110-50=15x
3. To solve this you subtract the 50$ from 110$ you get sixty dollars you do that to take out what he earned for his allowance. Then your equation is 60=15x so you divide each side by 15 and when you do that x=4
