Answer:
2 bananas per dollar
Explanation:
We can represent the correlation between the number of bananas to their cost in a ratio:
bananas : cost
8 : $4
To get the price rate of bananas in bananas per dollar, we can divide both sides of the ratio by 4 so that the cost of the bananas is $1.
bananas : cost
8 / 4 : $4 / 4
2 : $1
This means that the price rate of the bananas is 2 bananas per dollar.
