hi

OpenStudy (anonymous):

hi

OpenStudy (freckles):

let p represent the price of a single pretzel and d represent the price of a single drink one sentence says someone spent 3*d dollars and 3*p dollars for a total of 9 dollars. In equation form that looks like, 3d+3p=9 you can setup another equation using the other sentence. you will end up with a system of equations to solve.

OpenStudy (anonymous):

how can solve that?

OpenStudy (freckles):

did you get the other equation yet using the other sentence?

OpenStudy (anonymous):

no i dont know how to solve it

OpenStudy (freckles):

so you don't see how from the first sentence I got 3d+3p=9?

OpenStudy (freckles):

the second equation can be found from the 2nd sentence

OpenStudy (freckles):

4 drinks+2 pretzels=8.5 is what the second sentence says...

OpenStudy (freckles):

4d+2p=8.5 3d+3p=9 is the system you need to solve

OpenStudy (anonymous):

d 1.25 and p 1.75

OpenStudy (freckles):

right so you have found both the price of a single pretzel and the price of a single drink

OpenStudy (anonymous):

so how can i type that

OpenStudy (freckles):

what do you mean exactly?

OpenStudy (anonymous):

1.75?

OpenStudy (freckles):

you were asked to find the price of the pretzel you just found it above
