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

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

what i would say the best answer is a. 40.5
