Represent the proportional relationship described with an equation where p equals pillows and b equals beds:

four pillows for each bed

a) p = 4b

b) 4p = b

c) p =

4

b

d) b =

4

p

A) p = 4b

Step-by-step explanation:

We know that the equation for direct variation between two quantities x( independent variable ) and y( dependent variable )  is given by :

, where k is proportionality constant.

Let p = Number of pillows and b= Number of beds.

If four pillows require for each bed, then

Number of pillows = 4 x (Number of beds)

i.e. p = 4 x (b)

i.e. p =4b

Hence, the equation that represents the  proportional relationship described with an equation where p equals pillows and b equals beds:

p = 4b

Therefore , the correct answer is A) p = 4b.
