Answer 1

B The percentage change is 55%

Answer 2

Answer:

The approximate percent change is:

55%

Step-by-step 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

= $\dfrac{550-350}{350}\times 100\\\\=\dfrac{200}{350}\times 100\\\\=57.14\%$

which is approximately equal to :

55%
