Answer 1

b The percentage change is 55%

Answer 2

The approximate percent change is:

55%

Explanation:

It is given that:

The new number, 550, is 200 more than the original number.

Let the original number be: x

That means:

550=200+x

x=550-200

x=350

Now, the percent change is calculated as:

[(New number-Original number)/original number]×100

=
`(550-350)/(350)* 100\\\\=(200)/(350)* 100\\\\=57.14\%`

which is approximately equal to :

55%
