Question

The price of bananas can be determined by the equation p=0.45n where p is the price and n is the number of bananas. What is the constant of proportionality (unit rate)

Answer 1

The constant of proportionality is 0.45.

Explanation:

The constant of proportionality is the ration of two different quantities or is the unit value of a quantity.

The expression representing the price of bananas is:

`p=0.45n`

To determine the unit rate of bananas divide the price by the number of bananas.

`\text{Unit Rate}=(p)/(n)`

`=(0.45n)/(n)\\\\=0.45`

Thus, the constant of proportionality is 0.45.
