than Bella.

Answer 1

To determine how much more Jack earns per hour compared to Bella, let's calculate the hourly rates for both Bella and Jack using the provided data.

Bella's Earnings:

• At 10 hours, she earns $151.
• At 20 hours, she earns $302.

The earnings per hour can be calculated as follows:

• For Bella:
  • Earnings for 10 hours: $151 / 10 = $15.10 per hour
  • Earnings for 20 hours: $302 / 20 = $15.10 per hour
• Bella earns consistently $15.10 per hour.

Jack's Earnings:

• At 5 hours, he earns $96.
• At 15 hours, he earns $288.
• At 25 hours, he earns $480.
• At 35 hours, he earns $672.

Calculating Jack's hourly rate:

• For Jack:
  • Earnings for 5 hours: $96 / 5 = $19.20 per hour
  • Earnings for 15 hours: $288 / 15 = $19.20 per hour
  • Earnings for 25 hours: $480 / 25 = $19.20 per hour
  • Earnings for 35 hours: $672 / 35 = $19.20 per hour
• Jack earns consistently $19.20 per hour.

Comparison of Earnings: Now we compare the two hourly rates:

• Bella earns $15.10 per hour.
• Jack earns $19.20 per hour.

To find out how much more Jack earns compared to Bella:

• $19.20 - $15.10 = $4.10

Final Statement: Jack earns $4.10 more per hour than Bella.

Thus, in the answer blank, we would write:

Jack earns $4.10 more per hour than Bella.
