Ms. jackson and 3 of her friends went out for sushi. they order 6 rolls and 4 sodas. the soda is $3.75 less than the rolls. they spent a total of $70.50. what is the cost of one roll, write and equation and solve.

Ms. Jackson + her 3 friends = 4 people all together

Find how many would each person be getting/eating.
6 rolls / 4 people = 1.5 roll(s) a person

First, subtract 3.75 from 70.50.
70.50 - 3.75 = 66.75

Take 66.75 and divide that by 4 (people)
66.75 / 4 = ~ (about) 16.69

Lastly, take 16.69 and divide that by 1.5 (roll(s))
16.69 / 1.5 = ~ (about) 1.11 each roll

I'm not sure that is right but I tried :(: I hope this works and is right! :) Sorry if it isn't! :(
