Quiz 5-2 Real World Linear Equations

Jacob is looking for a job delivering pizzas. Different pizza shops have different payment methods for their delivery people.

1. Tino’s Pizza is offering Jacob $25 base pay and then $3 per pizza that he delivers.

a. Define the variables for this situation

• X: Total Money Made Y: Number of Pizzas

• X: Number of Pizzas Y: Total Money Made

• Variables should be numbers and not words

1. Fireplace Brick Oven Pizza showed Jacob his possible earnings, E, for delivering p pizzas with the equation E = 2.75p + 34 .

Neighborhood Pizza showed his possible earnings with the table below.

Pizzaz's Delievered: 2 4 6 10

Total Earinings: 43 48 53 63

A. Determine the slope for each of these jobs. **Hint jumps

• Fireplace Pizza Slope: 2.75

  Neighborhood Pizza Slope: 5/2= 2.50

• Fireplace Pizza Slope: 34 Neighborhood Pizza Slope: 43

• There is no rate of change when delivering Pizza

Determine and compare the y-intercepts for these two jobs **Hint remember to find your zero point

• Fireplace: $3.00 Neighborhood: $43.00- Neighborhood has a higher base pay by 40.00

• Fireplace: $34.00 Neighborhood: $38.00- Neighborhood has a higher base pay by 4.00

• Fireplace: 34.00 Neighborhood: 43.00- Neighborhood has a higher base pay by 9.00

Write the slope intercept equation for each pizza place

• Fireplace: y=2.75p+43 Neighborhood: y=2p+43

• Fireplace: y=34p+2.75 Neighborhood: y=38+2.50p

• Fireplace: y=2.75p+34 Neighborhood: y=2.50p+38

• There are no slope intercept equations for Pizza Delivery
