Question

Alice is searching online for tickets to a knicks game. Two weeks ago, the cost was $30. Now the cost is $39. What is the percent increase

Answer 1

Given:

Two weeks ago, the cost of tickets = $30

Now, the cost of tickets = $39

To find:

The percent increase.

Solution:

We have,

Initial value = $30

New value = $39

Formula for percentage increase is:

`\%\text{increase}=\frac{\text{New value - Initial value}}{\text{Initial value}}* 100`

Using this formula, we get

`\%\text{increase}=(39-30)/(30)* 100`

`\%\text{increase}=(9)/(3)* 10`

`\%\text{increase}=3* 10`

`\%\text{increase}=30`

Therefore, the percent increase in the cost of tickets is 30%.
