Question

FAN & MEDAL FOR HELP

Answer 1

3.A coffee shop pays Coffee Delivery Company A, a certain price for each disposable cup it orders plus a weekly delivery charge to remain on the driver’s delivery route. The cups are purchased in increments of 500. To quickly determine how much the coffee shop will be spending on cups before their arrival, the owner created the following table:




Cups Ordered

Price


0 $7
500 $25.50
1,000 $44
1,500 $62.50
2,000 $81
2,500 $99.50
3,000 $118

A.The price of the cups, p(x), is a function of the number of x cups ordered. Using the table, determine the average rate of change for the first 1,000 cups ordered and then for all 3,000 cups ordered. What does this tell you about the function?

Answer 2

the average rate is 18.5 between each of them

Answer 3

can u tell me how u got tht?? do u do f(b)-f(a)/b-a????

Answer 4

all I did was subtract 118-99.50
then 99.50-81 and so one
that showed they were all 18.5 apart

Answer 5

so on*

Answer 6

im sorry but I don't get how u do it

Answer 7

118-99.50=18.5
99.50-81=18.5
81-62.50=18.5
62.50-44=18.5
44-25.50=18.5

Answer 8

oh I get it now.

Answer 9

as for writing the formula I'm not sure how you'd write it

Answer 10

it ok but I think i'd have to do it tht way

Answer 14

First, think of the table as a list of (x,y) pairs
the first 3 pairs are
(0,7)
(500,25.50)
(1000,44)

To answer
determine the average rate of change for the first 1,000 cups

we want the change in y divided by the change in x
(in other words, find the slope between the start point (0,7) and the end point (1000,44)

can you do that ?

Answer 15

can u explain to me how to do that @phi

Answer 16

to find the slope between 2 points, find the difference in their y values
then find the difference in their x values
then divide: y difference divided by x difference

Answer 17
