The blueberry pies are sold to the grocer for $10.00 and the peach pies are sold for $9.00. The couple is able to sell all of the pies owing to their high quality. They use fresh ingredients. Sugar and flour are bought once a month. The price of sugar per pound is $1.40 and there are roughly 2 cups of sugar in one pound. The price of flour per pound is $0.36 and there are roughly 3.6 cups of flour in one pound.

On hand are 4 pounds of flour left from the previous month that must be used. There is no shortage of flour, sugar or fruit in the market for them to purchase. The ratio of blueberry pies to peach pies should be at most 4 to 9. The couple working together can make a blueberry pie in 10 minutes and a peach pie in 8 minutes.

Select one: a. 3B+2.5P -14.4 d. 0.3B+0.25P

Explanation / Answer

3.6 cups of flour is one pound

Each blueberry pies requires 3 cups of flour or 3/3.6 pounds of flour

Each Peach pies requires 2.5 cups of flour or 2.5/3.6 pounds of flour

Total flour available is 4 pounds

So,

3/3.6*B + 2.5/3.6*P <= 4

3B + 2.5P <= 4*3.6

3B + 2.5P <= 14.4

Ans B
