@mathstudent55 PLEASE HELP!

OpenStudy (mathstudent55):

Look at the table first. What is the cost of 2 doughnuts?

OpenStudy (volleyballlover55):

6

OpenStudy (mathstudent55):

Good. If 2 doughnuts cost $6, then what does 1 doughnut cost?

OpenStudy (volleyballlover55):

3

OpenStudy (volleyballlover55):

@mathstudent55 $3

OpenStudy (mathstudent55):

Correct. Now we know the price of the doughnuts is $3 for each one. We need to find out what is the price of each pie. For that we use the graph.

OpenStudy (volleyballlover55):

ok....

OpenStudy (mathstudent55):

Find a point on the graph that is easy to read. You need a point that is on the intersection of grid lines.

OpenStudy (123tatan):

It would be the same thing, you need to divide 20 by 2

OpenStudy (volleyballlover55):

10?

OpenStudy (mathstudent55):

@123tatan Did you ask this question? Do you think I am not explaining it well? Can you do a better job than I can?

OpenStudy (123tatan):

@mathstudent55 Chill I'm trying to help to.. It's not like I did it wrong.

OpenStudy (mathstudent55):

@123tatan I see that you can read a graph. How do you know the poster can do it too? Will you take his test for him?

OpenStudy (123tatan):

@mathstudent55 I told him how to do it not the answer...

OpenStudy (mathstudent55):

You read the graph for him which is what I wanted to see if he could do.

OpenStudy (volleyballlover55):

btw guys, im a she.. Lol ;)

OpenStudy (123tatan):

@volleyballlover55 Sorry about that then :P

OpenStudy (mathstudent55):

@volleyballlover55 Sorry. Look at the graph. You see that directly above 2 pies on the x-axis, the point on the line corresponds to $20. That means that 2 pies cost $20. You need to price of 1 pie.

OpenStudy (volleyballlover55):

ok so it would be $10 for 1 pie. :)

OpenStudy (mathstudent55):

Correct. Now read again the question. You need to find difference in price between 1 pie and 1 doughnut.

OpenStudy (volleyballlover55):

7?

OpenStudy (mathstudent55):

Correct. That is the answer.

OpenStudy (volleyballlover55):

yay! next :)

OpenStudy (volleyballlover55):

OpenStudy (mathstudent55):

Pls, do 1 question per post according to OS rules.

OpenStudy (volleyballlover55):

ok!

OpenStudy (volleyballlover55):

sorry
