Answer 2

Answer:

Option D - $\frac{\ 2.70-\ 2.40}{\ 2.40}=\frac{p}{100}$

Step-by-step explanation:

Given : Last year, the price of the hamburger Wonderful Whopper was $2.40. This year the price increased to $2.70. If p is the percent increase in the price of the Whopper.

To find : Which proportion can be used to compute p?

Solution :

Original price - $2.40

New price - $2.70

Percentage increase = p

The increased in percentage formula is

$\% \text{Increase}=\frac{\text{New-Original}}{\text{Original}} \times 100$

Substitute the value,

$p=\frac{\ 2.70-\ 2.40}{\ 2.40} \times 100$

or $\frac{\ 2.70-\ 2.40}{\ 2.40}=\frac{p}{100}$

Therefore, option D is correct.
