D) What does the point (4: 24) represent in the context of the situation pertaining to JJ Scooters?

E) Which scooter company has the better rate per hour?

Answer 1

Answer:

See the graph with both lines attached

A) From the tables we see the constant change of values in the second column and the initial value is zero.

This represents a proportional relationship for both tables.

B) Revel

• Rate of change is 5 per hour, the equation is:
• y = 5x, where y is cost, x - is the number of hours

Scooters

• Rate of change is 6 per hour, the equation is:
• y = 6x, where y is cost, x - is the number of hours

C) When x = 12,

• y = 5*12 = $60 for Revel
• y = 6*12 = $72 for Scooters

D) The point (4, 24) represents that:

• The cost of 4 hours is $24

E) The second table has confusing titles (days and number of cell phones) but if we assume its same as the first table, then Revel has lower rate as 5 < 6.

Comparing the prices and the graph, Revel has better rate per hour.
