Final answer:
Greg will earn $150, and Ike will earn $125.
Step-by-step explanation:
To determine how much each person will earn after working for 10 hours, we can find their hourly rates and multiply them by the number of hours. Greg earns $30 for 2 hours, so his hourly rate is $15. Therefore, he will earn $15 x 10 = $150. Ike earns $50 for 2.5 hours, so his hourly rate is $20. Therefore, he will earn $20 x 10 = $200. Option 1: Greg will earn $150, and Ike will earn $125.
