After increasing the price by 1,200.00 pesos, the price of a tv set becomes 1,600.00 pesos. What is the percentage increase

To calculate the percentage increase, we can use the formula:

\[
\text{Percentage Increase} = \left( \frac{\text{Increase in Price}}{\text{Original Price}} \right) \times 100
\]

- Increase in Price = 1,200.00 pesos
- Final Price = 1,600.00 pesos
- Original Price = Final Price - Increase in Price = 1,600.00 - 1,200.00 = 400.00 pesos

Now, plug the values into the formula:

\[
\text{Percentage Increase} = \left( \frac{1,200.00}{400.00} \right) \times 100 = 300\%
\]

Thus, the percentage increase is **300%**.
