Greg earns $30 in 2 hours of work. His friend Ike earns $50 In 2.5 hours work. If both Greg and Ike work 10 hours on weekend, which statement is correct?
A. Ike will earn $50 more then Greg
B. Ile will earn $5 more than Greg
C. Greg will earn $50 more than Ike
D. Ike and Greg will earn the same amount
To compare their hourly rates, we divide the amount earned by the number of hours worked:
Greg's hourly rate: $30 ÷ 2 = $<<30/2=15>>15
Ike's hourly rate: $50 ÷ 2.5 = $<<50/2.5=20>>20
Since Ike's hourly rate is higher than Greg's, Ike will earn more than Greg for the same amount of hours worked. Therefore, option B is correct. Ile will earn $5 more than Greg.
To determine which statement is correct, we need to compare the hourly rates of Greg and Ike. We can calculate their hourly rates by dividing the amount earned by the number of hours worked.
Greg earns $30 in 2 hours, so his hourly rate is $30 / 2 hours = $15 per hour.
Ike earns $50 in 2.5 hours, so his hourly rate is $50 / 2.5 hours = $20 per hour.
Now, we need to calculate their earnings after working 10 hours on the weekend.
Greg's earnings would be $15 per hour * 10 hours = $150.
Ike's earnings would be $20 per hour * 10 hours = $200.
Comparing their earnings, we can see that Ike will earn $200 - $150 = $50 more than Greg.
Therefore, statement A is correct: Ike will earn $50 more than Greg.
To determine which statement is correct, we need to calculate the total earnings of Greg and Ike for 10 hours of work.
Greg earns $30 in 2 hours, so his hourly rate is $30 / 2 = $15 per hour.
Therefore, Greg will earn $15 x 10 = $150 for 10 hours of work.
Ike earns $50 in 2.5 hours, so his hourly rate is $50 / 2.5 = $20 per hour.
Therefore, Ike will earn $20 x 10 = $200 for 10 hours of work.
Comparing their earnings:
A. Ike will earn $50 more than Greg. (Incorrect - Ike will earn $50 - $30 = $20 more than Greg)
B. Ike will earn $5 more than Greg. (Incorrect - Ike will earn $200 - $150 = $50 more than Greg)
C. Greg will earn $50 more than Ike. (Incorrect - Ike will earn $200 - $150 = $50 more than Greg)
D. Ike and Greg will earn the same amount. (Correct - Ike will earn $200 and Greg will earn $150, so they will not earn the same amount.)
Therefore, the correct statement is D. Ike and Greg will earn the same amount.
