Answer:4
Step-by-step explanation:
Ex (increase, such as taxes or price hike):
I want to increase $5 by 20%.
That means I would have to find the product of $5 and 120%.
$5*1.20=6
If you increase $5 by 20%, you will get $6.
Ex (decrease, such as a discount or a special deal):
I want to decrease $5 by 20%.
That means I would have to find the product of $5 and 80%.
$5*.80=4
If you decrease $5 by 20%, you will get 4.
The easiest way of calculating discount is, in this case, to multiply the normal price $280 by 20 then divide it by one hundred. So, the discount is equal to $56. To calculate the sales price, simply deduct the discount of $56 from the original price $280 then get $224 as the sales price.
