Answer:
$5.09 cents
Explanation:
Given the following question:
20% of 6.36
In order to find the answer, we will calculate using the formula for percentages then subtract that answer from the initial amount to have our answer.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{20\times6.36}{100}=20\times6.36=127.2\div100=1.272[/tex]
[tex]=1.272[/tex]
Round:
[tex]1.272[/tex]
[tex]2 < 5[/tex]
[tex]1.27[/tex]
Now subtract:
[tex]6.36-1.27=5.09[/tex]
[tex]=5.09[/tex]
After a 20% decrease the price is now "$5.09 cents." Which means this was the price before the 20% increase.
Hope this helps.
