d1i1m1o1n [39]

The cash price of the article is 88 cedis.

In this question, the article has a price, but paid in cash, there are two discounts.

Price of 115 cedis.
Discount of 15%, thus, 1 - 0.15 = 0.85 is paid, that is, the price is multiplied by 0.85.
Discount of 10%, thus 1 - 0.1 = 0.9 is paid, that is, the price is also multiplied by 0.9.

Thus, the cash price is:

$P = 115\times0.85\times0.9 = 88$

The cash price of the article is 88 cedis.
