Answer:
15 cars to break even
Step-by-step explanation:
The profit of the baseball team can be calculated as:
P = 5x - 75
Where x is the number of cars that they have to wash. So, 5x is the received money and 75 is the spent money.
So, to break even the profit is equal to 0, so the equation is:
0 = 5x - 75
Now, we can solve for x. so, adding 75 on both sides:
0 +75 = 5x - 75 + 75
75 = 5x
Dividing by 5, we get:
75/5 = 5x/5
15 = x
Therefore, the baseball team has to wash 15 cars to break even.
This value of x is the x-intercept of the graph of the profit and it means that when they wash 15 cars, the profit is equal to 0.
