Explanation:

Question 1:

Step1: Determine earnings and expenses

Earnings per minute: $1, so for 20 minutes, earnings = LXI0. Expenses: $6 (fixed for travel).

Step2: Calculate total pay

Total pay = Earnings - Expenses = \(20 - 6 = 14\).

Step1: Determine earnings and expenses

Earnings per minute: $1, for 30 minutes, earnings = LXI0. Expenses: $6.

Step2: Calculate total pay

Total pay = \(30 - 6 = 24\).

Step1: Determine earnings and expenses

Earnings per minute: $1, for 50 minutes, earnings = LXI0. Expenses: $6.

Step2: Calculate total pay

Total pay = \(50 - 6 = 44\).

Answer:

14
