Question

The cost of a t-shirt was $30. Now the t-shirt costs $37.50. What is the percent of change? Do the work on your own paper and write your answer as a number.

Answer 1

25%

Explanation:

Given that,

Initial cost of a t-shirt = $30

Final cost of a t-shirt = $37.50

We need to find percent of change. The percentage change in any value is given by :

`\%=\frac{\text{final value-initial value}}{\text{initial value}}* 100\\\\=(37.5-30)/(30)* 100\\\\=25\%`

Hence, the percentage error is 25%.
