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. Create a graph showing the amount of each fruit you can buy.

Answer 1

Let

x = lb of Cherries

y = lb of Grapes

4x + 2.50y <= 6

x + y >= 2

Answer 2

Let's say x=cherries and y=grapes. (desmos only does x and y :( ).
the equation would be 9=4x+1.50y
