Answer:

To calculate Harry's total bill, we need to consider the cost of labor and the cost of the parts. Let's break it down step by step:

1. Labor cost:

The mechanic charges $24 per hour for labor, and the labor was charged for 1 3/4 hours.

Convert 1 3/4 hours to a mixed fraction: 1 3/4 = (4 + 3)/4 = 7/4 hours.

Labor cost = Labor rate per hour * Labor hours

Labor cost = $24/hour * 7/4 hours

To calculate this, we can multiply the numerators (24 * 7) and the denominators (1 * 4) separately:

Labor cost = ($24 * 7) / (1 * 4)

Labor cost = $168 / 4

Labor cost = $42

2. Cost of parts:

The mechanic replaced the spark plugs for $9, the air filter for $12, and the fuel filter for $4.79.

Cost of parts = Spark plugs cost + Air filter cost + Fuel filter cost

Cost of parts = $9 + $12 + $4.79

Cost of parts = $25.79

3. Total bill:

Total bill = Labor cost + Cost of parts

Total bill = $42 + $25.79

Total bill ≈ $67.79

Therefore, Harry's total bill, including labor and the cost of parts, is approximately $67.79.
