Missing part of the question is;
Find a formula for the number of seats sold if the ticket price is P dollars.
Answer:
(680 - P)/3
Step-by-step explanation:
A) Let x be equal to the number of seats and hence we can conclude that (160 - x) is equal to the number of seats after the increase in price.
Similarly, the increase in ticket price would be equal to (P - 200)
Due to the fact that for every $3 increase, the number of seats decrease by 1, the equation that links the change in the number of seats to the change in ticket price is;
P - 200 = 3(160 - x)
P = 3(160 - x) + 200
Making x the subject;
P = 480 - 3x + 200
P = 680 - 3x
3x = 680 - P
x = (680 - P)/3
Answer:
172 ft
Step-by-step explanation:
120 + the other 1/4 is 160 160 + 12 is 172
“Three decimal places” is the same as “the nearest thousandth.” So, for example, if you are asked to round 3.264 to two decimal places it means the same as if your are asked to round 3.264 to the nearest hundredth. Some questions, like the example below, will ask you to “show your answer correct to two decimal places."
