Katia and Mel are trying to raise money for a charity. Each of them will buy the candy for an initial cost of 2$ per pound. Katia is going to buy candy from M&M and sell each pound of candy for $3 a pound. Mel is going to buy Sugarfina and sell it for $6 a pound. They must raise at least $900.
"what's the least amount of pounds of M&Ms and Sugarfina each GIRL needS to sell IN ORDER to satisfy the constraints?"
x = M&Ms y = Sugarfina
3x+6y > 900 y >100
Domain and Range
Solving the Problem - Graph
1. Graph both inequalities on a grid and shade the intersection 3x+6y >900
The x intercept is: 3x+6(0) = 900 3x = 900 3 3 x=300
The y intercept is: 3(0) + 6y = 900 6y = 900 6 6 y = 150
