Question

The original selling price of a share of stock was d dollars. the selling price for a share of the same stock at a later date was represented by the expression 1.15(0.95d). which description could explain what happened to the price of the share of stock

Answer 1

By simplifying the given expression representing the selling price of the same stock, we get an answer of,
1.15(0.95d) = 1.0925d
The result above shows that the share of the stocks increased value by 0.0925d where d is the original price.

Answer 2

The price was first discounted by 5% and then the price was increased by 15%

Explanation:

Original selling price of a share of stock = d dollars

Now, the selling price for a share of the same stock is represented by the equation : 1.15·( 0.95 × d)

Multiplication of the selling price d by 0.95 represents that the original price was discounted by 5% therefore, d was multiplied by 100 - 5 = 95%

After that the resulting price is again multiplied by 1.15

Which shows that the price is increased by 15% because the actual was 100% after increase of 15% it becomes 115% or 1.15 times

Hence, the price was first discounted by 5% and then the price was increased by 15%
