Barry had the following:

8 bananas

12 apples

20 kiwi

32 peaches

8 grapefruit

4 mangos

88 total

Step-by-step explanation:

Each of the amounts of fruit can be written in terms of one variable. Starting with bananas as 'x', we can then make different values of 'x' to produce all the other numbers of fruits:

bananas = x

apples = 2x (twice as many bananas)

kiwi = 2.5x (5/6 of applies and bananas combined = 5/6 (3x) or 2.5x)

peaches = 3.5x + 4 (sum of bananas and kiwis plus four = x + 2.5x + 4)

grapefruit = x (half as many apples = 2x/2)

mango = 0.5x (20% of kiwi = (0.2) (2.5) x)

88 = x + 2x + 2.5x + 3.5x + 4 + x + 0.5x

88 = 10.5x

8 = x (bananas)

apples = 2x or 16; kiwi = 2.5x or 20, peaches = 3.5x + 4 = 32, grapefruit = x or 8, mangos = 0.5x or 4
