A stadium has 45,000 seats. Seats sell for $30 in Section A, $24 in Section B, and $18 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,168,800 from each sold-out event. How many seats does each section hold?

Answers

a + b + c = 45,000
30a + 24b + 18c = 1,168,800 reduces to 5a + 4b + 3c = 194,800
a = b + c

b + c + b + c = 45,000
2b + 2c = 45,000
b + c = 22500 <=== this is A
c = 22500 - b

5a + 4b + 3c = 194,800
5(22500) + 4b + 3(22500 - b) = 194,800
112500 + 4b + 67500 - 3b = 194,800
b + 180,000 = 194,800
b = 194,800 - 180,000
b = 14,800 <===here is b

a = b + c
22500 = 14800 + c
22500 - 14800 = c
7700 = c <== here is c

so....A = 22,500, B = 14,800, and C = 7,700

You are scheduling a new delivery route and you need to find out how long it will take a driver to complete the route. You start the route at 9:50 A.M. and finish at 2:05 P.M. How long does it take to drive the route?

Answers

Answer:

4 hours and 15 minutes

Step-by-step explanation:

We have to find out how long it will take a driver to complete the route.

Time of start the route = 9:50 A.M.

Time of finish = 2:05 P.M.

We can convert the time of finish in 24 hours time

2:05 P.M = 14:05

Now we subtract start time from finish time.

14:05

- 09:50 [borrow 60 minutes to subtract 50 from 05]

04 : 15

It takes 4 hours and 15 minutes to drive the route.

The route will take four hours and fifteen minutes. If you start at 9:50 and count four hours, you'll get to 1:50, add ten to get to 2:00, then add 5 minutes to get to 2:05. Four hours plus ten minutes plus five minutes, 4:15.

- Mariana debe tomar dos pastillas; una cada 6 horas y otra cada 9 horas. Si a cierta hora toma las dos pastillas juntas, ¿después de cuantas horas volverá a tomarlas simultáneamente?

Answers

Answer:

Mariana takes the two pills together after 18 hours.

Step-by-step explanation:

Mariana must take two pills; one every 6 hours and another every 9 hours.

She take two pills together. Let she takes the two pills together after t hours at the time when she take initially.

To find the time to take the two pills together, take the least common multiple of 6 and 9.

6 = 2 x 3

9 = 3 x 3

So, the least common multiple is 2 x 3 x 3 = 18

So, she takes the two pills together after 18 hours.

Ten weeks ago Jerry bought stock at 211/2
; today the stock is valued at 203
/8
. We could say the stock
is performing at which of the following?
A. On par
B. Par equality
C. Below par
D. Above par

Answers

Since 211/2 = 105.5 and 203/8 = 25.375, it is quite clear that Jerry has lost money on this stock. So the correct answer is C. Below par.

Answer:

(c) Below par

Step-by-step explanation:

Ratio at which stock is bought = 211/2

= 105.5

Therefore, the par value = 105.5

Recent ratio of stock = 203/8

= 25.375

Value of stock today = 25.375

Since the ratio is decreased Hence, the value of stock is below par value.
