Question

The price of apples can be determined by the equation P=0.23n, where P is the price and n is the number of apples. What is the constant of proportionality (unit rate)

Answer 1

The constant of proportionality(Unit rate) is 0.23

Explanation:

Given equation is:

`P = 0.23n`

Here

P is the price and n is the number of apples

The price is usually directly proportional to quantity so the relationship can be written as:

P ∝ n

Removing the proportionality symbol, we get

P = kn

Comparing the given equation with this equation we get

k = 0.23

Hence,

The constant of proportionality(Unit rate) is 0.23
