Tems11 [23]

ince the problem is only asking for 4 years, we can just calculated it out year by year. Recall the formula for compounding interest: A = P(1+r)n, where A is the total amount, P is the principle (amount you start with), r is the interest rate per period of time, and n is the number of periods (in this case, r is annual interest rate, so n is number of years). At the beginning (Year 0), Lou starts off with 10000: A = 10000 At the end of Year 1, Lou earned interest on that amount, plus he has deposited another 5000: A = 10000(1.08) + 5000 End of Year 2, Lou's interest from the year 0 amount has compounded, he has started earning interest on the amount deposited last year, and he deposits another 5000: A = 10000(1.08)2 + 5000(1.08) + 5000 End of Year 3, same idea. Lou has earned compounding interest on all existing deposits, and deposits another 5000: A = 10000(1.08)3 + 5000(1.08)2 + 5000(1.08) + 5000 End of Year 4, same idea: A = 10000(1.08)4 + 5000(1.08)3 + 5000(1.08)2 + 5000(1.08) + 5000 = 36135.45

Tickets for a concert are $40 for main-floor seats and $25 for upper level seats. A total of 2000 concert tickets were sold. The
Tems11 [23]

Step-by-step explanation:

<u>to show how many tickets were sold:</u>

x = upper floor tickets

y = main floor tickets

x + y = 2000

<u>to show total amount of revenue:</u>

25x + 40y = 62,000

<u>Finding answer using both equations:</u>

x + y = 2000

multiply each side by 25

25x + 25y = 2000 × 25

25x + 25y = 50,000

25x + 40y = 62,000

-

25x + 25y = 50,000

-----------------------------------

15y = 12,000

^ this is column subtraction

<em>^ this column subtraction is done to isolate y so we can work with one value rather than 2</em>

15y = 12,000

divide each side by 15

12,000 ÷ 15 = 800

y = 800

x + y = 2000

x + 800 = 2000

x = 1200

Therefore 1200 upper-level tickets were sold

800 main floor tickets were sold

Answer:

2nd and 3rd ordered pair are on the graph

Step-by-step explanation:

Substitute the x- coordinate into the equation and if the value obtained is equal to the y- coordinate then it lies on the graph.

(1, 625 )

f(1) = - 25^{1+1} = - 25^{2} = - 625 ≠ 625 ← No

(0, - 25 )

f(0) = - 25^{0+1} = - 25^{1} = - 25 ← Yes

(- 1, - 1 )

f(- 1) = - 25^{-1+1} = - 25^{0} = - 1 ← Yes [ using a^{0} = 1 ]
