Solve: $20x + $25y ≤ $650

This is a system of equations. There is one problem though. If we have 2 variables, we need two equations to solve it. You only have one equation. We can however, get y in terms of x. Is that what you want to do?

OpenStudy (anonymous):

uhm, I have x ≥ 15 and y ≥ 10

OpenStudy (anonymous):

@wio does that help?

OpenStudy (anonymous):

Now you have more equations than you need. What exactly are you trying to do? Sorry I'm confused now.

OpenStudy (anonymous):

I'm trying to solve the first equation for my math class. I had to pretend I'm opening a clothing shop

OpenStudy (anonymous):

x = jeans y = dresses i need to make more than 15 jeans a day and 10 dresses a day.

OpenStudy (anonymous):

I will sell the jeans for $20 and the dresses for $25 @wio

OpenStudy (anonymous):

Sure, so what is the restriction?

OpenStudy (anonymous):

$20x + $25y ≤ $650 I need to find out how many jeans and dresses I an make a week without going over $650 @wio

You may have multiple solutions. You need to graph the following lines: y ≤ -4x/5 + 26 y ≥ 10 x ≥ 15 Graph them like you would normal lines, but shade under ≤ and above ≥ for y, and shade right of ≥ and left of ≤ for x. The area which overlaps all shading has ever solution point.
