The club sold 120 student tickets and 30 adult tickets.

Step-by-step explanation:

The cost of student ticket= $12

The cost of adult ticket= $20

The total cost of 150 tickets sold= $2040

Check for which option gives you the answer as $2040

Option A)

The cost of 30 students= 30*12= $360

The cost of 120 adults= 120*20= $2400

The total cost of 150 tickets= 360+2400= $2760 (exceeds 2040)

Option B)

The cost of 120 students= 120*12= $1440

The cost of 30 adults= 30*20= $600

The total cost of 150 tickets= 1440+600= $2040 (correct answer)

Option C)

The cost of 100 students= 100*12= $1200

The cost of 50 adults= 50*20= $1000

The total cost of 150 tickets= 1200+1000= $2200 (exceeds 2040)

Option D)

The cost of 50 students= 50*12= $600

The cost of 100 adults= 100*20= $2000

The total cost of 150 tickets= 600+2000= $2600 (exceeds 2040)

In basketball there are 1,2, and 3 point shots. In the last game sarah scored a total of 25 points by making 13 total baskets. S

ollegr [7]

Answer:

3 , 6 , 4

Step-by-step explanation:

Given:

There are three groups of shots in basketball.

First group carry = 1 point

Second group carry = 2 points

Third group carry = 3 points

Sarah scored a total of 25 points by making 13 total baskets.

She made twice as many 2 point shots as she did 3 point shots.

Question asked:

How many of each type of shot did she make ?

Solution:

Let number of baskets, she made which carry 3 points = $x$

Then, number of baskets, she made which carry 2 points = $2x$

Total number of baskets, she made = 13

Then, number of baskets, she made which carry 1 points = $13-(x+2x)=13-3x$

Now,

Sarah scored a total number of points = 25

$3\times x+2\times2x+1(13-3x)=25\\3x+4x+13-3x=25\\4x+13=25$

Subtracting both sides by 13

$4x=25-13\\4x=12$

Dividing both sides by 4

$x=3$

By substituting the value:-

Number of baskets, she made which carry 3 points = $x$ = 3

Number of baskets, she made which carry 2 points = $2x$ = $2\times3=6$

Number of baskets, she made which carry 1 points = $13-3x=13-3\times3=13-9=4$

Thus, she made 3 baskets of 3 points, 6 baskets of 2 points and 4 baskets of 1 point.
