  1. Fluffy’s Tacos sells burritos depending on the meat in it. On Monday’s Sophie usually has cravings for a chicken burrito, which costs $6. On Tuesday’s Sophie usually craves pork instead, which costs $7. Sophie receives the same total benefit for the burritos she craves, regardless of the meat in it. The table below shows the total benefit Sophie receives from eating the burritos that she craves.

a.)How many burritos will Sophie buy on Mondays?

b.)How many burritos will Sophie buy on Tuesdays?

c.)On a Tuesday, how many chicken burritos would Sophie buy if chicken burritos cost $4?

d.)How low does the price of burritos have to be for Sophie to buy 4 tacos on a Tuesday?
