19. Suppose Misty purchased the 10-Day Ticket Package that
costs $80 plus $20 per day.
a. Complete the table below for the total cost of the lift
tickets in the 10-day package for 0 through 6 days. Be sure
to include the initial cost of $80.
302
Number of
Days

Total Cost of
Lift Tickets
b. Explain how you know the data in the table above is linear.

Part a) The table in the attached figure (see the explanation)

Part b) see the explanation

Step-by-step explanation:

Let

y ----> the total cost of  Lift Tickets

x ----> the number of days

we know that

The linear equation in slope intercept form is given by

where

m is the slope or unit rate of the linear equation

b is the initial value or y-intercept pf the linear equation

In this problem we have

The slope is equal to

The y-intercept is equal to

substitute

Complete the table

Find the value of y for each value of x

For x=0 day

For x=1 day

For x=2 days

For x=3 days

For x=4 days

For x=5 days

For x=6 days

Part b) Explain how you know the data in the table above is linear

The data in the table is linear, because satisfy the equation of the linear equation

where

x is the variable independent or input value (the number of days)

y is the variable dependent or output value (the total cost of  Lift Tickets)

answer: huh
