If you're not including tax, here's how you will do it:
15% can be converted to .15
you would then multiply .15 by 75.50
.15 * 75.50 = 11.325
since you can't give someone half of a penny, you must round up, getting 11.33
now you add 11.33 to 75.50
11.33 + 75.50 = 86.83
so, her bill would come out to be $86.83
Don't forget the "$" sign!

Answer:
150 minutes (2.5 hours)
Step-by-step explanation:
We must consider that the total time that the radio program lasted represents the 100%.
Of that 100% we are told that 20% is dedicated to commercials. So the 30 minutes of commercials correspond to 20% of the air time, which can be represented in the following table:
Percentage of time time
20% ⇒ 30min
and we are looking for how long the show was on the air (the 100%).
So updating the table( I will call x the total time on the air):
Percentage of time time
20% ⇒ 30min
100% ⇒ x
This reationship between three values can be solve by the<u> rule of three</u>: multiply the cross quantities on the table (100 by 30) and divide by the remaining amount (20):
x = 100*30 / 20
x= 3000 / 20
x = 150 minutes
The radio show was 150 minutes (2.5 hours) long.
