If the base price of a concert ticket is 30$ and a handling subcharge of 15% is added to the price, what is the total cost of ticket?

34.50$

Step-by-step explanation:

To calculate the value of the surcharge we need to multiply the base price of the ticket (30$) by the rate of the surcharge (15% or 0.15).

30 * 0.15 = 4.50

Then we add this surcharge (4.50$) to the base price of the ticket (30$) to get the total value of (34.50$).
