Answer:
On sale at a deficit of -20% from the original price is saying that the item is at 80% of its original value.
Converting percentages using decimals is a very easy way to fine original values.
So:
$76.80 = 80% of the original value
convert the 80% into a decimal = 0.80
The maths:
$76.80 ÷ 0.8 = $96.00
$96.00 = the original value.
Answer: The original price is $96
Step-by-step explanation:
Since 76.8 is the discounted price after 20% was taken off, we know that 76.8 is 80% of the original price. My way is to set up a equivalent fractions relation thing (I don’t know what to call it), and for this problem it looks like this:
80/100 = 76.8/?
the numerator is the part, or discounted price, and the denominator is the whole, or original price.
Using equivalent fractions, we can find out that ? = 96.
