PROPORTIONS AS A PROBLEMSOLVING TOOL FOR MARKON
The following brief review of proportions from Book 1 will make the
next problems easier to solve. Proportions are composed of two equal ratios.
A ratio contains two related quantities in fraction form.
Problem: If 95% of something is $50, what is 100% of it? Let S be the unknown.16. Set up a proportion to solve each problem.Step 1: Set up a ratio for "95% of the unknown represents $50." 95% / $50
Step 2: Set up another ratio for "100% represents the unknown, S." 100% / S
Step 3: Set up a proportion, making the two ratios equal to one another.
Step 4: Cross multiply.Step 5: Solve the resulting equation. 0.95 x S = 50
S = 50 / 0.95 = $52.63

Example: Suppose a handheld calculator cost $7.50 and the markon is 25% on the SP. What do you do with the 25%? You cannot multiply 25% times $7.50, because markon is to be based on the SP.

COMPUTING MARKON ON THE COST
Markon is sometimes computed on the cost rather than on the SP. As
you will soon see, the computation is very simple, but be certain you understand
the principle involved. The formula is:
Markon = Markon % x CostProblem: A pen and pencil set costs $15 and is to be marked up 40%. What is the amount of the markon and the SP? Study the bar chart below.
What is the 40% markon to be based on? _____(b)_____

MODEL COMPUTATION
The computation for the problem illustrated in the bar chart is shown
below. First compute the markon; then compute the SP.
Step 1: Compute markon, using the formula Markon = Markon % x Cost.
