Part C: Explain how the equations from Part A and Part B diffe

answer:

a)

b)

c) Part A only considers revenue whereas Part B considers the expense.

Step-by-step explanation:

a)

Rhett made a total of $250.

He charged $75 per car. We assume that he washed number of cars in total. He earns: by washing cars.

With an addition of $50 as tips: , his total reaches 250.

The equation is:

b)

Total profit: $250

Total number of cars:

Earning from car wash:

Total tips earned: $35

Expense per car:

Profit = Revenue  - Cost

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
