Question

(c) The amount of money collected, M, is directly proportional to the number of tickets sold, t. (i) Represent this information as an equation in terms of M, t and an appropriate constant, k. [1]

Answer 1

A proportion between two variables can be represented as:

y = kx, where y is the dependent variable, x is the independent variable, and k is a constant.

In this question:

M = dependent variable (depends on the number of tickets sold)

t = independent variable

k = constant

Substituting the values in the equation:

M = kt

Answer:

M = kt
