Answer:
f(10)=342
Step-by-step explanation:
f(10)= 3(10)^2+6(10)-18
complete your exponet first and multiply 6(10)
f(10)=3(100)+60-18
multiply the 3(100)
f(10)=300+60-18
add and subtract all the numbers together
f(10)=342

<h3>What is Mean?</h3>
The mean is the simple definition of the average of a bunch of numbers. In statistics, one of the markers of central tendency is the mean.
The average is referred to as the arithmetic mean.
It's the ratio of the number of real observations to the total number of observations.
The owners of a manufacturing company conducted a survey to determine the mean income of the customers who prefer the company’s brand of clothing.
From a random sample of 100 customers, it was determined that their mean income was $47,600.
Based on statistical analysis, the entire population mean must be close to $47,600.

(I) The 15 represents the money earned for each ticket sold
In other words the 15 is the cost of each ticket.
(II) The 700 represents the costs inquired when organizing the dance
In other words...how much it costs to throw the dance.
<u>Explanation</u>
Since t is the number of tickets and the function shows profit we know that every step on the left has some aspect to do with the profit....for ever ticket (t) sold there is an addition of 15 dollars...or for every 1 ticket sold $15 is earned....or each ticket costs 15 dollars
The -700 shows that 700 dollars must be subtracted from the total income from selling tickets....since this is looking for profit which is income-costs and we have already determined that 15t represents the income we know that the 700 must represent the costs of throwing the dance.
