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
= [tex]\dfrac{550-350}{350}\times 100\\\\=\dfrac{200}{350}\times 100\\\\=57.14\%[/tex]
which is approximately equal to :
55%
