Exploring Slope-Intercept Form in Real-Life Scenarios

What does Jerry include in the charge for the coins?

• Just the cost of the coins

• Cost of coins and a service fee

• Cost of coins and shipping

• Cost of coins, shipping, and taxes

What equation does Jerry use to calculate the total charge for coins?

• Y = MX + B

• Y = X - C

• Y = X + C

• Y = MX - B

How much does Jerry charge for 10 coins?

• $342.45

• $329.50

What does the slope in Jerry's equation represent?

• The shipping cost per coin

How much more did Dave pay than Zach if he bought 5 more coins?

• $164.75

• $164.50

• $165.00

• $164.25

Why is it unnecessary to know the number of coins Zach bought to determine how much more Dave paid?

• Because Zach got a discount

• Because Dave paid double

• Because the price per coin is fixed

• Because Dave didn't actually buy coins

How do we know Jerry charged zero for shipping during the sale?

• Because Jerry announced free shipping

• Because the equation was altered to remove the shipping cost

• Because the shipping cost was included in the price of the coins

• Because the total cost didn't change

If Carrie bought twice as many coins as Lou, how does this affect their total cost?

• Carrie's total cost is half of Lou's cost

• Carrie's total cost is twice Lou's cost

• Carrie's total cost is less due to a bulk discount

• Carrie's total cost is the same as Lou's

What alteration to the equation indicates a sale with no shipping charges?

• Subtracting 12.95 from the total

• Removing the 12.95 from the equation

• Adding 12.95 to the total

• Doubling the 12.95 in the equation
