Decrease £28 by 7%? im stuck on my homework

Mathematics

Answer:

   £26.04

Step-by-step explanation:

The long way is to figure 7% of £28, then decrease that quantity by the amount you figured.

  0.07 ×  £28 =  £1.96

  £28 - 1.96 =  £26.04

__

I prefer to realize that the 100% of the value, decreased by 7%, will be 93% of the value. Then only one calculator operation is required.

  0.93 ×  £28 = £26.04

_____

<em>Comment on percent</em>

Some folks get confused by percents. "Percent" essentially means "per hundred". The symbol % is a shorthand way to write /100, which means exactly the same thing. That is, 7% = 7/100 = 0.07. (Similarly, ‰ is a shorthand way to write /1000.)

<em>Comment on percentage increase or decrease</em>

When you're talking about a quantity decreased by some amount, as "£28 decreased by £7",  you mean the value £7 is subtracted. When you say "decreased by 7%", the interpretation is different. We don't mean that £28 is decreased by 0.07 (to give £27.93); rather we mean £28 is decreased by 7% of £28. That is 7% of £28 is subtracted from £28.
