Question

The Drama Club held a car wash to raise money. The equation y = 15x represents the amount of money y club members made for washing x cars. Identify the constant of proportionality.

Answer 1

15

Explanation:

Given that:

y = 15x

y = amount of money made by club members made for washing cars

x = number of cars washed

From the equation given ;

Amount made is directly proportional the number of cars washed

Mathematically,

y α x

y = kx

Where k = constant of proportionality

Comparing the given equation with

y = kx

y = 15x

k = 15 = constant of proportionality
