Answer 1

Calculation of the Initial Cost and the Discounted Amount

To find the initial cost of the item and the amount by which it was discounted, we can use the information provided.

Let's assume the initial cost of the item is represented by x.

According to the given information, after a 20% discount, the item's price became 64.8 currency units.

We can set up the following equation to represent this:

x - 20% of x = 64.8

To solve this equation, we need to calculate 20% of x and subtract it from x:

x - 0.2x = 64.8

Simplifying the equation:

0.8x = 64.8

Dividing both sides of the equation by 0.8:

x = 64.8 / 0.8

Calculating the value of x:

x = 81

Therefore, the initial cost of the item was 81 currency units.

To find the amount by which the item was discounted, we can subtract the final price from the initial price:

Discounted amount = Initial cost - Final cost

Discounted amount = 81 - 64.8

Calculating the discounted amount:

Discounted amount = 16.2

Therefore, the item was discounted by 16.2 currency units.

So, the initial cost of the item was 81 currency units, and it was discounted by 16.2 currency units.
