Question

Hi I rlly could use some help with this! I’m not the best at math and I’m rlly struggling with this assignment its a couple questions long! I will give brainiest and 10 given points!
Info:In this activity, you will find out how many cars the baseball team needs to wash before it starts making a profit. The team spent $75 setting up the car wash, and they are charging $5 per car for a wash.
1.The first step in modeling this situation is to track how much money the baseball team will take in. Write an equation to represent the amount of money collected in dollars, y, in terms of the number of cars washed, x. Ignore the setup cost.

2.The equation you wrote in part A accounts for money collected. However, it does not account for the money the baseball team spent to set up the car wash. What do you need to do to the equation in part A to account for the setup cost?

3.Now that you have an idea of how much money the baseball team will collect and how much it will spend, you’re ready to write an equation modeling the situation. Write an equation representing the profit made on the car wash in dollars, y, in terms of the number of cars washed, x, after expenses.

4.You now have an equation to model the finances of the car wash. What is the value of the profit when the baseball team washes 0 cars? What point represents this value? What does the y-value of this point mean in terms of the problem?

5.The baseball team will break even when the amount of money it has received equals the amount of money it spent. In other words, the team breaks even when the profit is equal to zero. How many cars does the baseball team have to wash to break even? What point represents this value? What does the x-value of this point mean in terms of the problem?

Pls help!!!

    1. Let y represent the amount of money earned, and x the number of cars they wash. Then

    y = 5x

    Why? Each car wash costs $5. So no car washes means no earnings; 1 car wash earns $5; 2 washes earn $10; 3 washes earn $15, and so on, so that x car washes generate $5x.

    2. No matter how many cars they end up washing, they will have spent $75 to set up the operation, so you subtract 75 from the equation is part (1).

    3. Taking into account the setup cost of $75, the profit they make is given by

    y = 5x – 75

    4. When x = 0, meaning no cars get washed, the profit is -$75, meaning the team loses $75.

    5. Set the profit function equal to 0 and solve for x :

    5x – 75 = 0

    5x = 75

    x = 75/5

    x = 15

    So the team has to wash at least 15 cars to break even.

    Answer:

    The setup cost is $75. To account for the setup cost, you need to subtract 75 from the right side of the equation obtained in part A.
