18 less than twice the number of people who saw the show on Friday. Saturday’s show had an audience of 174. How many people saw the show on Friday?
Let the number of people who saw the show on Friday be x.
Twice the number of people who saw the show on Friday is 2x.
18 less than twice the number of people who saw the show on Friday is 2x-18.
Saturday’s show had an audience of 174, so 2x-18=174.
Adding 18 to both sides gives 2x=192.
Dividing both sides by 2 gives x=<<96=96>>96. Answer: \boxed{96}.
Let's solve this step-by-step.
Let's assume the number of people who saw the show on Friday is P.
According to the given information, Saturday's show had an audience of 174, so we have P = 2(174) - 18.
Now, let's solve for P.
P = 2(174) - 18
P = 348 - 18
P = 330
Therefore, 330 people saw the show on Friday.
