Answer:
See below.
Explanation:
John has 16 cups of apples and 15 cups of flour..
A pie needs 4 cups of apples and 3 cups of flour.
Apples: 16/4 = 4 he has enough apples to make 4 pies.
Flour: 15/3 = 5 he has enough flour to make 5 pies.
He can only make 4 pies, because of the amount of apples he has.
By making 4 pies, he uses all his apples, and he can make no cobblers.
x = 4 pies; y = 0 cobblers
Plot (4, 0).
A pie needs 2 cups of apples and 3 cups of flour.
Apples: 16/2 = 8 he has enough apples to make 8 cobblers.
Flour: 15/3 = 5 he has enough flour to make 5 cobblers.
He can only make 5 cobblers, because of the amount of flour he has.
By making 5 cobblers, he uses all the flour, and he can make no pies.
x = 0 pies; y = 5 cobblers
Plot (0, 5).
Now we calculate the amount of money.
At point (4, 0), 4 * $3 = $12
At point (0, 5), 5 * $2 = $10
Point (4, 0) shows a profit of $12 which is the most profit he can make.
