The student council at king high school is planning a winter dance. the function rule, p=15t-700, shows the relationship between the profit p, in dollars, and the number of tickets sold , t, for the dance.

a)in the function rule, p=15t-700,

(i) what is the practical meaning of 15?

(ii) what is the practical meaning of 700?

(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.

Explanation
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 profitfor ever ticket (t) sold there is an addition of 15 dollars...or for every 1 ticket sold $15 is earnedor each ticket costs 15 dollars

The -700 shows that 700 dollars must be subtracted from the total income from selling ticketssince 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.

model a: 9 presses

model b: 9 presses

Step-by-step explanation:

let x=model a and y=model b.

If asanji has 28 printing presses, we can say that x+y=18.

If he can print 1260 books in a day, we can say that 80x+60y=1260.

Now, We can solve the system of equation by solving an equation in terms of any variable. You can choose any variable. I chose x. x+y=18, So if we subract y from each side, we get x=18-y. Now, we can substitute that in the other equation. Thus, 80(18-y) +60y=1260. If we continue to solve for y, 1440-80y+60y=1260, 1440-20y=1260, subtract 1440 from each side, which gives you -20y=-180, and divide - 20 and you get y=9. Now, substitute the 9 in the x+y=18 to find x. Thus, x+9=18, and x=9. So, Asanji has 9 press of Model A and 9 presses of Model B.
