A company's stock was selling at
$16 a share. A month later, it was
selling at $20 a share. What is
the percent increase?
[?]%

Answer 1

old: $16

new: $20

percent increase

-> formula: (new-old / old) x 100

(20-16 / 16) x 100

4/16 x 100

0.25 x 100

answer: 25% increase

Answer 2

The percentage increase will be "25%".

According to the question,

Old selling price,

• $16

New selling price,

• $20

We know the formula,

→ $Percent \ increase = \frac{New \ selling \ price- Old \ selling \ price}{Old \ selling \ price}\times 100$

By putting the values,

                               $= \frac{20-16}{16}\times 100$

                               $= \frac{4}{16}\times 100$

                               $= 0.25\times 100$

                               $= 25$ (%)

Thus the above approach is appropriate.
