B	5+2c+1.75=20.755+2�+1.75=20.75
C	5c(2+1.75)=20.755�(2+1.75)=20.75
D	7c+1.75=20.757�+1.75=20.75

Answer 1

Hi Arianna,

Given: FIVE friends each ordered 2 cheeseburgers and a drink from McDonalds. The drinks cost $1.75 each, and the TOTAL cost of ALL their orders was $20.75.

c = cost of cheeseburgers,

Each friend had 2 cheeseburgers and 1 drink

So The cost per person is 2c + 1.75

Since there are 5 friends. The total cost would be 5 x (2c + 1.75) = 20.75

So Answer A
