Answer:

9 hours

Step-by-step explanation:

Using the initial ratio of 15 tickets in half an hour, you can set up a proportion (equivalent ratios) to find the amount of time it would take to sell 270 tickets:

$\frac{tickets}{time}=\frac{15}{0.5}=\frac{270}{x}$

Where 'x' is the amount of time to seel 270 tickets.

Cross-multiply: 0.5(270) = 15x or 135 = 15x

Divide: 15x/15 = 135/15 or x = 9 hours
