Part A: Maci made $170 grooming dogs one day with her mobile dog grooming business. She charges $60 per appointment and earned $50 in tips. Write an equation to represent this situation. (4 points) Part B: Logan made a profit of $210.00 as a mobile groomer. He charged $75.00 per appointment and received $35.00 in tips, but also had to pay a rental fee for the truck at $10.00 per appointment. Write an equation to represent this situation. (4 points) Part C: Explain how the equations from Part A and Part B differ. (2 points)

Step-by-step explanation:

Part A

Let x = the number of visits

Let y = the total amount of money earned.

y = 60x + 50

This is a little bit sloppily worded. I think the question means that no matter how clients she had in one day, her tips amounted to a total of 50 dollars.

The equation is the general equation for what happened. To make it reflect the number of visits for Maci, y = 170

170 = 60x + 50     Subtract 50

120 = 60x             Divide by 60

120/60 = x

x = 2

So she had 2 appointments.

Part B

Let the profit = 210

Let the number of appointments = x

Let the income from the appointments = 75x - 10x = 65x

y = 65x + 35

Part C

They differ in the way the income is calculated. In part B you have to know what to do with the 10 dollars / appointment,  See part B to see how to handle the 10 dollars per appointment.

Part A has no such expense.  

your answer is
