Using proportions, it is found that the total cost of three bottles of detergent is of $11.55.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
A certain brand of laundry detergent is manufactured for $4.40 and then marked up 25% by the local store before selling, hence the price of each bottle is given by:
P = 4.40 x 1.25 = $5.50.
The store offers a 30% discount with the purchase of three or more bottles of the detergent, hence the total cost is given by:
T = (3 x 5.50) x 0.7 = $11.55.

If you would like to know what is 16% of 25, you can calculate this using the following steps:
16% of 25 = 16% * 25 = 16/100 * 25 = 4
Result: 16% of 25 is 4, so the correct result would be d. 4.
