Specifically:
#15+15(.65)#

Generically:
#X+X(Y)#
Where #X# represents the cost of the item, and #Y# represents the increased cost, in the form of a decimal.

The cost of the computer case was $15. The price increase can be represented by 65% more than $15 dollars. These two values are separate, considering that there is a consideration for the original price and a consideration for the increase of the price. Alternatively, the values can be linked by simply multiplying the computer case's cost by 1.65, which yields the same result in the end. This indicates that the computer case is selling for 65% more than its initial cost. Either one will work, but the #X+X(Y)# expression, in my opinion, is better suited because it isolates and acknowledges both the initial cost and the price increase based on that initial cost.

undefined The expression that represents the price of the computer case in the store is $ \$15 + (65\% \times \$15) $.
