Solution:
Given that,
The new menu had 20% more dishes than the previous menu
The previous menu had D dishes
Therefore,
Previous menu = D dishes
New menu = 20 % more dishes than previous menu
Which means,
New menu = 20 % of previous menu + previous menu
Therefore,
New menu = 20 % of D + D
Solve the above equation
![New\ menu = 20 \% * D + D\\\\New\ menu = (20)/(100) * D + D\\\\New\ menu = 0.2 * D + D\\\\New\ menu = 0.2D + D = (D)/(5) + D = 1.2D](https://img.qammunity.org/2021/formulas/mathematics/middle-school/zx6j1e553675kpzbipjom6ujx3lbe6rsjo.png)
Therefore, new menu has 1.2D dishes
