Question

Alex had a cellphone that cost $ 125. She recently bought a new phone that cost $200. What was the percent increase in the prices of the phones ?

Answer 1

The Solution to Question 2:

Given that Alex bought:

old phone price = $125

new phone price = $200

We asked to find the percent increase in the prices of the phones.

To calculate the required percent increase, we shall use the formula below:

`\text{ percent Increase =}\frac{\text{ change in price}}{\text{old phone price}}*100`
`\begin{gathered} \text{ percent increase = }(200-125)/(125)*100 \\ \\ =(75)/(125)*100=60\text{\%} \end{gathered}`

Therefore, the correct answer is 60%
