Sometimes the unit price on two sizes of the same product will be the same. When this is the case, how will different kinds of d
mamaluj [8]

The different type of discount effected on the prices of two similar products having the same unit price may either increase or decrease the total unit price on the discounted sale price of the items.

Taking an hypothetical scenario :

50 ml of Product A = $100

60 ml of product A = $100

<u>Discount on sale of 60ml size on purchase of two or more units </u> : 10% off

Discounted price of 60 ml size :

Initial product cost on purchase of 3 units = ($100 × 3) = $300

Discounted price = (100 - 10)% × $300 = $270

<u>Discount on sale for 50ml size on purchase of two or more units</u> : $20 off

Discounted price of 50ml size :

This means $20 is deducted from any purchase of two or more units ;

Hence, purchasing 2 units of the 50 ml product will cost ; (

($100 × 2) - $20

$200 - $20 = $180

Therefore, the discount effected on the cost of product which has the same unit price may either decrease or increase the total cost of one product relative to the other.
