Number of people in committee = 3

Number of ways of selecting committee with atleast 2 girls :

We either have :

(2 girls 1 boy) or (3girls 0 boy)

(4C2 * 6C1) + (4C3 * 6C0)

nCr = n! ÷ (n-r)!r!

4C2 = 4! ÷ 2!2! = 6

6C1 = 6! ÷ 5!1! = 6

4C3 = 4! ÷ 1!3! = 4

6C0 = 6! ÷ 6!0! = 1

(6 * 6) + (4 * 1)

A high school drama department sold 238 tickets for their performance.
o   An adult ticket cost $6.75.
o   A student ticket cost $3.50.
o   The high school drama department collected $1,252.25 in ticket sales.
How many student tickets were sold? 

Answers

Let x = number of student tickets
Ley y = number of nonstudent tickets

then we know that the total number of tickets is 537

so

x + y = 537

if we multiply the cost of a ticket by the number of tickets we can also get the total $

3.2x + 5.9y = 2185.5

now we have two equations and two unknowns and we can find the value for these unknowns

lets use substitution

x + y = 537 that means that x = 537-y

substitute this value in the second equation

3.2(537-y) + 5.9y = 2185.5

1718.4 - 3.2y +5.9y = 2185.5

1718.4 + 2.7y = 2185.5

2.7y = 2185.5 - 1718.4

2.7y = 467.1

y = 173

x + y =537

x + 173 = 537

x = 364

Answer:

$6.75 + $3.50 = X

X ÷ $1,252.25

Step-by-step explanation:

$6.75 + $3.50 = $10.25

$10.25 ÷ $1,252.25 = 0.00818526652

Answers

Answer:

the price for one pretzel was $1.75

Step-by-step explanation:

3d + 3p = 9

3d = 9 -3p

d = 3 - p

replace d = 3 - 9 into 4d + 2p = 8.5

4d + 2p = 8.5

4(3 - p) + 2p = 8.5

12 - 4p + 2p = 8.5

-2p = 8.5 - 12
