Students are shown a hyperbola and asked to identify it as such.

Students are given the equation of a hyperbola and asked to identify the hyperbolic graph out of a set of 4 graphs.

The student is shown an exponential graph and asked to evaluate the function at some given value.

They are also asked whether or not the model is valid for all real inputs, but they only give a yes/no response. The reasoning is explained in the advice but is not required from students.

Students are given an exponential equation and asked to evaluate it at two points.

The constants in the exponential are randomised.

Students are shown an exponential curve and asked to identify it as either linear, parabolic, hyperbolic or exponential.

Students are shown an exponential function formula and asked to identify the correct graph, given an exponential, a hyperbola, a parabola and a line.

Students are shown an exponential graph and asked to choose the correct formula for the graph.

Shows an exponential graph displaying the value of an investment under compound interest. Students have to identify the type of graph and answer 3 questions about the value of the investment from the graph.

Data from a compound interest are shown in a table. Students are asked to compute the value of an investment, and to identify the type of graph.

Students are given a formula for compound interest and asked to evaluate it for given initial investment values.

4 questions from a set of 12 on elementary day-to-day advertising mathematics

Given reach and frequency, calculate TARPS. Multiple choice question.

Given Campaign budget and cost per acquisition, calculate the number of sales.

Given a budget and the number of views, calculate the cost per view. All numbers are randomised.

Calculate a percentage of a number.

Find a percentage of a given population. Percentage and population are both randomised.

A proportions question. Given the total number of impressions, and the number of impressions that were clicked, what percentage were clicked?

Read a value from a table. There are 36 possible questions.

Given n = k%, what is 100%?

percentage rate is 0.5, 1, 1.5 or 2%. Number of impressions is randomised.

Given number of TARPs and total price, calculate the Cost per TARP.

Given the cost for 1, 1000, 10000 or 100000 impressions, what is the cost for 1000?

Given potential audience, the percentage that view, and the percentage of these that click, calculate the CPA by dividing potential audience by clickers. 

All numbers randomised.

Find a percentage of a number (number of TARPs spent on breakfast programs), then divide by the number of programs to find the average number of TARPs per program.

clicks = budget/CPC

All numbers are randomised.

Given a campaign budget and a CPM, calculate the number of impressions.

Given a total budget and the cost of each sale for three different scenarios, which scenario produces the most sales?

Calculate CTR given number of clicks and number of impressions served.

percentage CTR is 0.5, 1, 1.5 or 2%. Number of impressions is randomised.

Given budget and number of sales, calculate the cost per acquisition (CPA)

n = 1, 1000, 10000, or 100000.
