The price of meal at a restaurant is 200% more than the 100$, it was a couple of decades ago. What is the price now?

netineya [11]

Answer:

The price now is 300$.

Step-by-step explanation:

The problem is related to percentages.

It is provided that the price of meal at a restaurant a couple of decades (20 years) ago was 100$.

Now the price is 200% more than what it was 20 years ago,i.e. the price increased by 200%.

Compute the new price as follows:

$New-Price=100\$+[100\$\times200\%]\\= 100\$+[100\times\frac{200}{100}]\$\\ =100\$+200\$\\=300\$$

Thus, the price of the meal now is 300$.
