Using proportions and the markup concept, it is found that the cost to store is of $12.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The markup price of 80% means that the selling price is of 180% = 1.8 of the cost to store of x. The selling price is of $21.60, hence:
1.8x = 21.60
x = 21.60/1.8
x = $12.
The cost to store is of $12.
