Answer:

132 people bought balcony seats and 450 people bought ground seats.

Step-by-step explanation:

We want to solve the system of equations:

\left\{        \begin{array}{ll}            15b+10g=6480 \\            b+g=582        \end{array}    \right

We can solve this by using substitution. From the second equation, we can subtract <em>b</em> from both sides:

g=582-b

In the first equation, we can divide both sides by five:

3b+2g=1296

Substitute:

3b+2(582-b)=1296

Distribute:

3b+1164-2b=1296

Simplify:

b+1164=1296

Solve for <em>b: </em>

<em />b=132<em />

<em />

Using the modified equation again, substitute:

g=582-(132)

Evaluate:

g=450

Therefore, 132 people bought balcony seats and 450 people bought ground seats.

Answer:

y = 3/4x + 7

Step-by-step explanation:

Put it in point-slope form:

y - 4 = 3/4(x - -4)

y - 4 = 3/4(x + 4)

y - 4 =3/4x + 3

y = 3/4x + 7
