So the diameter is 2 yards.

Dave sold 60 general and reserved tickets for a concert. He sold general tickets for $10 each and reserved tickets for $15 each

Answer:

The system is of equations is:

\left\{        \begin{array}{ll}            10g+15r=725 & \quad  \\            g+r=60 & \quad         \end{array}    \right.

Where g is the amount of general tickets and r is the amount of reserve tickets.

35 general tickets and 25 reserve tickets were sold.

Step-by-step explanation:

Let general tickets be represented by g and reserved tickets be represented by r.

Each general ticket sells for $10 each and reserved tickets $15 each. Dave collected a total of $725. Thus:

10g+15r=725

And a total of 60 tickets were sold. Hence:

g+r=60

Our system of equations is:

\left\{        \begin{array}{ll}            10g+15r=725 & \quad  \\            g+r=60 & \quad         \end{array}    \right.

We can solve by substitution. First, divide both sides of the first equation by 5:

2g+3r=145

Next, we can subtract a variable (r in this case) from the second equation:

g=60-r

Substitute:

2(60-r)+3r=145

Distribute:

120-2r+3r=145

Simplify:

120+r=145

Subtract:

r=25

Using the previous equation:

g=60-r

Substitute and evaluate:

g=60-(25)=35

So, 35 general tickets and 25 reserve tickets were sold.
