Calculate the values for the row 'c + d' and '20 * (c + d)'

1. Calculate c + d for each column:

• 7 + 8 = 15
• 12 + 8 = 20
• 15 + 15 = 30
• 40 + 1 = 41
• 50 + 0 = 50
• 0 + 200 = 200

2. Calculate 20 * (c + d) for each column:

• 20 * 15 = 300
• 20 * 20 = 400
• 20 * 30 = 600
• 20 * 41 = 820
• 20 * 50 = 1000
• 20 * 200 = 4000
