Answer:
6 bananas, 24 bapples.
Step-by-step explanation:
If Omar has 4 times as many apples as bananas: then if a is the number of apples and b is the number of bananas, then:
Let's say there are b bananas
Therefore there must be 4b apples
In total that gives 5b fruit.
Therefore since there are 30 fruit in all:
5b = 30
Therefore, b = 6
And since there are 30 fruit overall, 30 - 6 = 24
So there 24 apples overall and 6 bananas.
