Question

15DANCE TICKETS WERE SOLD IN ONE HALF HOUR. IF THIS RATE CONTINUES HOW LONG WOULD YOU EXPECT IT TO TAKE TO SELL 270 tickets.

Answer 1

9 hours

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:

`(tickets)/(time)=(15)/(0.5)=(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
