Answer:

1050 ways

Step-by-step explanation:

Total Number of red balls = 5

Total Number of blue balls = 5

Total Number of white balls = 7

Number of red balls selected = 3

Number of blue balls selected = 4

Number of red balls selected = 5

Using the multiplication and combination relation :

nCr * nCr * nCr

Red balls = 5C3

Blue balls = 5C4

White balls = 7C5

Using calculator:

5C3 * 5C4 * 7C5 = 10 * 5 * 21

(10 * 5 * 21) = 1050 ways

A concert organizer anticipates selling 4,000 tickets and that a quarter of these will be sold at 20% reduction of original pric
Deffense [45]

Answer:

$ 15.79

Step-by-step explanation:

Let x be the price of full ticket,

∵ Total number of tickets = 4000,

Quarter of 4000 tickets = \frac{4000}{4} = 1000,

Remaining tickets = 4000 - 1000 = 3000,

Since, if the price of each ticket is reduced by 20%,

Then the new price of each ticket = (100 - 20)% of x

= 80% of x

= 0.80x,

According to the question,

The total price of quarters of ticket + total price of remaining tickets = $ 60000

= 0.80x × 1000 + x × 3000 = 60,000

800x + 3000x = 60,000

3800x = 60,000

⇒ x ≈ 15.79

Hence, the price of full ticket is approximately $ 15.79.
