Answer 1

Given:

Crispy Clover introduced a new menu that has 20% more dishes than the previous menu

The previous menu had "D" dishes.

To find:

The expression which will represent the no. of dishes of the new menu of Crispy Clover

Solution:

No. of dishes in the previous menu = D

Let "N" represent the no. of dishes in the new menu of Crispy Clover.

Now, according to the question, we will find the expression for the no. of dishes in the new menu, through the following equation,

N = D + [20% of D]

⇒ N = D + [$\frac{20}{100}\:\times\:D$ ]

⇒ N = D +  [$\frac{1}{5}\:\times\:D$] ← option (A)

Thus, the final expression for the no. of dishes Crispy Clover's new menu has is  $\boxed{\bold{N = D\: +\: \frac{1}{5}D }}$ .
