The club sold 120 student tickets and 30 adult tickets.

<u>Step-by-step explanation:</u>

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

<u>Option A)</u>

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)

<u>Option B)</u>

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 <u>(correct answer)</u>

<u>Option C)</u>

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)

<u>Option D)</u>

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)

If h(x) = (f o g)(x) and h(x) = sqrt(x+5), find g(x) if f(x) = sqrt(x+2)
agasfer [191]

Answer:

  • g(x) = x + 3

Step-by-step explanation:

<h3>Given</h3>
  • h(x) = (f ο g)(x)
  • h(x) = \sqrt{x+5}
  • f(x) = \sqrt{x+2}
<h3>To find</h3>
  • g(x)
<h3>Solution</h3>

<u>We know that:</u>

  • (f ο g)(x) = f(g(x))

<u>Substitute x with g(x) and solve for g(x):</u>

  • \sqrt{x+5} = \sqrt{g(x)+2}
  • x + 5 = g(x) + 2
  • x + 3 = g(x)
  • g(x) = x + 3
