A restaurant sells tea for $1.50 plus $0.05 per refill a gas station store sells tea for $0.50 plus $0.50 per refill?

lutik1710 [3]

Answer:

Part a) $y=0.05x+1.50$

Part b) $y=0.50x+0.50$

Part c) The graph in the attached figure

Part d) see the explanation

Step-by-step explanation:

The complete question is

A restaurant sells tea for $1.50 plus $0.05 per refill. A gas station store sells tea for $0.50 plus $0.50 per refill.

Part a) Write a linear function for the price of tea at restaurant

Part b) Write a linear function for the price of tea at gas station store

Part c) Graph both equations

Part c) Compare the lines in terms of slope and y-intercept

Let

y -----> the price of tea in dollars

x -----> the number of refills

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value (value of y when the value o x is equal to zero)

Part a)

At restaurant

we have that

The slope or unit rate is equal to

$m=\$0.05\ per\ refill$

The initial value or y-intercept is equal to

$b=\$1.50$

substitute

$y=0.05x+1.50$

Part b)

At gas station store

we have that

The slope or unit rate is equal to

$m=\$0.50\ per\ refill$

The initial value or y-intercept is equal to

$b=\$0.50$

substitute

$y=0.50x+0.50$

Part c) Graph both equations

we know that

The easiest way to graph a line is with two points

Find the intercepts of the line

At restaurant

$y=0.05x+1.50$

The y-intercept is the point (0,1.50)

The x-intercept is the value of x when the value of y is equal to zero

For y=0

$0=0.05x+1.50$

$x=-30$

The x-intercept is the point (-30,0)

Plot the points and join to graph the line

see the attached figure

At gas station store

$y=0.50x+0.50$

The y-intercept is the point (0,0.50)

The x-intercept is the value of x when the value of y is equal to zero

For y=0

$0=0.50x+0.50$

$x=-1$

The x-intercept is the point (-1,0)

Plot the points and join to graph the line

see the attached figure

Part c) Compare the lines in terms of slope and y-intercept

The slope or unit rate at the restaurant is less than the slope at the gas station store

$\$0.05\ per\ refill < \$0.50\ per\ refill$

The initial value or y-intercept at the restaurant is greater than the initial value at the gas station store

$\$1.50 > \$0.50$

D Intersect E {2, 3, 5, 7}
F Different D {12, 16, 20}
