The table below shows the price in dollars for the number of roses indicated is the price proportional to the number of roses ex
makvit [3.9K]

Answer:

Price of roses is proportional to the number of roses.

Step-by-step explanation:

Let the price of roses are proportional to the number of roses.

Equation representing this phenomenon will be,

P = k(R) ⇒ k = \frac{P}{R}

where 'P' = price of the roses

R = Number of roses

k = Proportionality constant

If we substitute the values of P and R and we get the same value of constant 'k', then the equation will be true.

For R = 3 and P = $9  

k = \frac{9}{3}

k = 3

For R = 6 and R = 18

k = \frac{18}{6}

k = 3

K is same in both the conditions, therefore, Price of roses are proportional to the number of roses.
