OpenStudy (anonymous):

im thinking

OpenStudy (jadeishere):

a. 0.50x + 0.80y = 240.00 or 1/2x + 4/5y = 240

OpenStudy (anonymous):

i was going to say tht lol

OpenStudy (abdela25):

oh yeah ok i think ik how you got that

OpenStudy (jadeishere):

want me to explain it?

OpenStudy (abdela25):

so would y=-5/8x+300 and yes please

OpenStudy (jadeishere):

eeks i solved for x So i got 0.50x from the fifty cents as the amount of iced tea and 0.80y from the amount of the lemonade 240 as the overall price to get the equation to the y = mx + b just do the opposite operation on both sides of the = sign, like you did

OpenStudy (abdela25):

oh ok so my final answer which was y=-5/8x+300 was correct ? & it think im understanding this a lot better now

OpenStudy (jadeishere):

and yeah, i believe you got the rigt equation for that use this graphing site to help, it's wonderful!! http://www.geogebra.org/webstart/geogebra.html

OpenStudy (abdela25):

ok thank you so much so this site should help me graph it and what about part c ?

OpenStudy (jadeishere):

let me see about part c and yeah, this site is souly based on graphing, save it to your favorites on your computer, if possible

OpenStudy (abdela25):

ok thank you will do and part c is in the attached picture

OpenStudy (jadeishere):

Okay, so graph the equation on the site and then find different combinations that will add up to 240 so example (idk if it would work in this case) 34(x) + 206(y) = 240 THAT'S JUST AN EXAMPLE

OpenStudy (abdela25):

OOOOH ok i get it now haha thanks soo much ^_^

OpenStudy (jadeishere):

Yep :P i help when i can :)
