A sandwich store charges a delivery fee to bring lunch to an office building. One office pays $33 for 4 turkey sandwiches. Another office pays $61 for 8 turkey sandwiches. 1) Make a table comparing total cost in dollars, y, to number of turkey sandwiches, x. Be sure to label your column headers. Include a row that shows the cost of just the delivery fee (hint: zero sandwiches). Show the rate of change somewhere in your table.

2) Graph the relationship between total cost in dollars, y, to number of turkey sandwiches, x. Be sure to label your axes.

3) Write an equation (in any form) that represents the relationship between total cost in dollars, y, to number of turkey sandwiches, x.

4) Use your equation to determine the cost of 99 turkey sandwiches, plus delivery. Show all work.

I only need the last 2 wich are 3 and 4

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

50- 250 is correct i did that one too

step-by-step explanation:

96 39 cause 135 -96=39 im smart (i used a calculater)
