A deli sells small, medium, and large sack lunches. Each bottle of water costs $1, and each apple costs $1. Each sandwich costs s dollars. Some customers buy sack lunches, and some customers buy items separately. Amy buys 8 sandwiches and 12 waters. Her total cost is 8s + 12. Bob buys 8 small sack lunches. These sack lunches include 1 sandwich, 1 water, and 1 apple. His total cost is 8(s + 2). Cathy buys 4 medium sack lunches. These sack lunches do not include water. Her total cost is 4(2s + 3). How many sandwiches and how many apples are in each medium sack lunch that Cathy buys? Show your work or explain your answer.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

6.5

step-by-step explanation:

you said it was in the question

~courtney

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
