a surf shop makes profits of $150 for each surfboard and $100 for each wakeboard. the owner sells at least 3 surfboards and at least 6 wakeboards per month. the shop owner wants to earn at least $2000 per month. graph all possible combinations of ..
If the shop owner wants to earn at least $2000 per month, then
150x + 100y >/= 2000
100y >/= 2000 - 150x
y >/= 20 - 1.5x
We also know that x >/= 3 and y >/= 6
So we can graph the 3 inequalities. Where the regions all intersect represent all possible combinations of x and y which are the number of surfboards and wakeboards he must sell to earn at least $2000.
