algebra (word problem)
posted by catalyst
you are in charge of bringing snacks to a picnic. you decide to buy grapes and pretzels. the grapes are $2.39 per pound and the pretzels cost $1.89 a bag. you have $11 to spend. write an equation that models to different amounts of grapes and pretzels that you can buy.
I think I need to write this in y=mx+b formula.. if that's possible..
y=0.79x+4.60
is that right?
thanks in advance

You would first of all have to define what the x and y represent.
From your equation I concluded that
y is the number of pounds of grapes and x the number of pounds of pretzels.
Why is it necessary to change the equation to the form you have, I would write it as
189x + 239y = 1100
Your equation is correct.
