Answer:

Adult tickets sold =  225

Student Tickets sold =  375

Step-by-step explanation:

Let:

Adult tickets sold = x

Student Tickets sold = y

Total tickets sold = 600

So, we can write: x+y = 600

Total money collected = 3037.50

Cost of 1 Adult ticket = $6.00

Cost of one Student ticket = $4.50

So, we can write: 6x+4.5y=3037.50

Now, we get a system of equations, that if solved we can find values of x and y

Let:

x+y = 600--eq(1)\\6x+4.5y=3037.50--eq(2)

We can solve using substitution method.

Finding value of x from eq(1) and putting it in eq(2)

We\:have\\x+y=600\\x=600-y

Put in eq(2)

6x+4.5y=3037.50\\6(600-y)+4.5y=3037.50\\3600-6y+4.5y=3037.50\\-1.5y=3037.50-3600\\-1.5y=-562.5\\y=\frac{-562.5}{-1.5}\\y=375

So, we get value of y = 375

Now put value of y in eq(1) to find value of x

x+y=600\\Put\:y=375\\x+375=600\\x=600-375\\x=225

So, we get value of x = 225

The Tickets sold will be:

Adult tickets sold = x = 225

Student Tickets sold = y = 375

Answer:

Simplifying by collecting like terms

Step-by-step explanation:

Given

See attachment for complete question

Required

The missing step

The missing step is at step 2.

At step 1, we have:

\frac{1}{2} - 2x +1 = -\frac{13}{2}

At step 2, we have:

\frac{3}{2} - 2x= -\frac{13}{2}

What she did at step 2, is that:

She collected like terms; 1 and \frac{1}{2}

Then she simplified the like terms: 1 + \frac{1}{2} =\frac{3}{2}

<em>Hence (a) is correct</em>
