a. the company charges per ride at least 5$ and an extra 2$ per mile

b.the equation we will choose is slope intercept since we know the

y-intercept which is the cab flat rate .

y=mx+b

where

m :is the slope

b:is the y-intercept

y:total amount

x. is the milage

total amount=2x+5.

c.the slope will be 2$ which is the change in amount per mile.the y-intercept will be the cab's flat rate.

Step-by-step explanation:

Given:

Mr. Harris has 48 pencils and 30 notebooks.

To find the number of packages he can make with each package have same number of each item.

Solution:

Number of pencils = 48

Number of notebooks = 30

In order to find the number of packages he can make with each package have same number of each item, we will find the greatest common factor of the given numbers.

<em>To find the G.C.F., we will list down the prime factors of each.</em>

$48=2\times 2\times 2\times 2\times 3$
