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

y = kx
y = 15x
k = 15 = constant of proportionality

A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is the number of 3-point questions and y is the number of 5-point questions, the system shown represents this situation.
x + y = 24
3x + 5y = 100
What does the solution of this system indicate about the questions on the test?
The test contains 4 three-point questions and 20 five-point questions.
The test contains 10 three-point questions and 14 five-point questions.
The test contains 14 three-point questions and 10 five-point questions.
The test contains 20 three-point questions and 8 five-point questions.
