Question

Cherries cost ​$4​/lb. Grapes cost ​$1.50/lb You can spend no more than ​$9 on​ fruit, and you need at least 3 lb in all. Write the equation(s) in slope intercept form

Answer 1

1.5y= -4.5x+9 or y= -3x+6

and y= -x+3

Explanation:

First, you need to make a system of linear equations.

x=pounds for cherries

y=pounds for grapes

This would be:

4x+1.5y=9

x+y=3

Then, change the equations into slope intercept form.
