The number of apples and bananas Tina bought are 12 and 8 respectively.
How to find the number of apples and banana in the list?
She bought 20 apples and bananas for her class.
Apples cost $1.50 each. Bananas cost $1.25 each
let
x = number of apples
y = number of bananas
Therefore,
x + y = 20
1.50x + 1.25y = 28
Hence,
1.50x + 1.50y = 30
1.50x + 1.25y = 28
0.25y = 2
y = 2 / 0.25
y = 8
x = 20 - 8
x = 12
Therefore, numbers of apples is 12 and the numbers of bananas is 8.
