Question

The Fruit Mart sells variety packs. The small pack is $1.80 and contains three bananas, two apples, and one orange. The medium pack is $3.05 and contains four bananas, three apples, and three oranges. The family size is $4.65 and contains six bananas, five apples, and four oranges.

The Mart is planning a “single” pack with one banana, apple and orange.

How much should they charge for it to be consistent with the given prices?

Answer 1

Your system of equations are as follows if B = Banana, A = Apple, & O = Orange

3B + 2A + O = 1.80

4B + 3A + 3O = 3.05

6B + 5A + 4O = 4.65

Solving for each we obtain B = .20, A = .45, O = .30

So, the single pack would be .2 + .45 + .3 = .95
