HELP!!!!!! I'M DESPERATE!!!!!!!!!!! Directions: Select all the correct answers. Linda had a garage sale. She set up three tables at the garage sale and all items on the same table cost the same amount. On table A, items cost $1.25 each. On table B, items cost $1.35 each. On table C, items cost $1.50 each. Tommy, Denise, Brayden, Arielle, Erik, and Salena all have the same amount to spend at the garage sale and each person bought items off of just one table. The purchases made are shown below.

Ok, do you know how much money each person had?

OpenStudy (anonymous):

Sadly nope

OpenStudy (thedj4jc):

Well, it said that they all started with the same amount of money but each bought from a different table. At first I guessed they had $15, but found that they each had $20.

OpenStudy (anonymous):

Oh good go on :D

OpenStudy (anonymous):

So how do I figure it out?

OpenStudy (thedj4jc):

Let's solve which table Arielle bought items from first. Table A - $1.25, Table B - $1.35, and Table C - $1.50. Subtract 6.50, the amount of money she got back, by 20. What do you get?

OpenStudy (anonymous):

$13.50

OpenStudy (thedj4jc):

Ok, good. She bought 10 items, multiply the prices from the tables by 10 to find 13.50 as your answer.

OpenStudy (anonymous):

Table B

OpenStudy (thedj4jc):

Good! Does that make sense?

OpenStudy (anonymous):

Yes, yes it does thank you so much!
