Question

The cost of a video game increased in price from $20 to $39. What was the percent of the increase?

Answer 1

The price of the video game increased by 95%, which is calculated by subtracting the original price from the new price, dividing the increase by the original price, and then multiplying by 100 to get the percentage.

Step-by-step explanation:

To calculate the percent increase in the price of the video game, we can follow these steps:

Subtract the original price from the new price to find the increase in cost: $39 - $20 = $19.

Divide the increase by the original price to find the increase in terms of the original price: $19 / $20 = 0.95.

Multiply the result by 100 to convert it to a percentage: 0.95 × 100 = 95%.

Therefore, the price of the video game has increased by 95%.

Answer 2

For this exercise you need to use the following formula to calculate the Percent of Increase:

`PercentIncrease=\frac{Final\text{ }value-Starting\text{ }value}{|Starting\text{ }value|}\cdot100`

In this case, you can identify that (according to the information given in the exercise):

`\begin{gathered} Starting\text{ }value=20 \\ Final\text{ }value=39 \end{gathered}`

Therefore, you can substitute values into the formula and evaluate. The result is:

`\begin{gathered} PercentIncrease=(39-20)/(|20|)\cdot100=(19)/(|20|)\cdot100=95 \\ \end{gathered}`

The answer is: 95%
