Directions: Solve for the unknown variable.
1 \( 4 + 3(2m - 5) = 7 - 2(m - 3) \)
Solution: m =
2 \( 9 - 4(k + 2) = 3(2k - 1) - 4 \)
Solution: k =

Two catering companies determine their total charge in dollars for an event based on \( m \) hours of service:
Chef Express \( \$60 \) equipment fee plus \( \$30 \) per hour for \( (m + 2) \) hours, minus a \( \$10 \) promotional discount.
Gourmet Delight \( \$25 \) setup fee plus \( \$20 \) per hour for \( (2m - 1) \) hours, plus an additional \( \$40 \) cleanup fee.
For what value of \( m \) will the total charges of both catering companies be equal?
A \( m = 5 \)
B \( m = \frac{13}{2} \)
C \( m = \frac{9}{2} \)
D \( m = 7 \)

Two liquid storage tanks are being monitored in a laboratory experiment over \( t \) minutes:
- Tank A: Holds \( 25 \) liters initially, then receives inflow at \( 3(4t - 1) \) liters plus a \( 8 \)-liter buffer.
- Tank B: Holds \( 85 \) liters initially, but drains at \( 2(3t + 2) \) liters with an additional \( 6 \)-liter loss.
Construct a linear equation representing when both tanks hold an equal volume of liquid, and solve for \( t \).
A \( t = 3 \)
B \( t = \frac{5}{2} \)
C \( t = \frac{7}{2} \)
D \( t = 2 \)

Two student clubs are raising funds over \( k \) school weeks:
Beta Club Starts with \( \$30 \), earns \( \$4 \) per item on \( (3k - 2) \) items sold, and receives a \( \$5 \) alumni gift.
Robotics Club Starts with \( \$63 \), earns \( \$2 \) per ticket on \( (k + 4) \) tickets, and receives a \( \$6 \) sponsor bonus.
After how many weeks, \( k \), will both clubs have accumulated the exact same total amount?
A \( k = 4 \)
B \( k = \frac{11}{2} \)
C \( k = 7 \)
D \( k = 5 \)
