Answer 2

Task A: Two Masters Painting Christmas Ornaments

To determine if the two masters will be able to complete the order of painting 1500 Christmas ornaments, we need to calculate the total number of ornaments each master can paint in the given time frame.

Master 1: - Paints 20 ornaments per hour.

Master 2: - Paints 25 ornaments per hour.

Working hours: - Master 1 works 5 days, 8 hours per day. - Master 2 works 4 days, 6 hours per day.

Let's calculate the total number of ornaments each master can paint:

Master 1: - Total working hours: 5 days * 8 hours/day = 40 hours - Total ornaments painted by Master 1: 40 hours * 20 ornaments/hour = 800 ornaments.

Master 2: - Total working hours: 4 days * 6 hours/day = 24 hours - Total ornaments painted by Master 2: 24 hours * 25 ornaments/hour = 600 ornaments.

Now, let's calculate the total number of ornaments painted by both masters:

Total ornaments painted: 800 ornaments + 600 ornaments = 1400 ornaments.

Since the total number of ornaments painted by both masters is 1400, which is less than the order quantity of 1500 ornaments, they will not be able to complete the order within the given time frame.

Task B: Two Masters Painting Christmas Ornaments

To determine how many ornaments the first master can paint per hour, given that the second master paints 15 ornaments per hour and together they painted 2800 ornaments in total, we can set up the following equation:

Let x be the number of ornaments the first master can paint per hour.

The equation can be written as: x + 15 = total ornaments painted per hour by both masters.

Given that the second master paints 15 ornaments per hour, we can substitute this value into the equation:

x + 15 = 2800 ornaments/hour.

Now, let's solve for x:

x = 2800 ornaments/hour - 15 ornaments/hour = 2785 ornaments/hour.

Therefore, the first master can paint approximately 2785 ornaments per hour.
