Answer:
[tex]\text{John's hourly earnings}=\$9.75[/tex]
[tex]\text{Amy's hourly earnings}=\$10[/tex]
Amy earns $0.25 more than John.
Step-by-step explanation:
We have been given that John earn $97.50 for 10 hours of work.
Let us find hourly earnings of Jake by dividing total earnings by total times as:
[tex]\text{John's hourly earnings}=\frac{\$97.50}{10}[/tex]
[tex]\text{John's hourly earnings}=\$9.75[/tex]
Therefore, John earns $9.75 per hour.
We are also told that Amy earned $120 for 12 hours of work.
Let us find hourly earnings of Amy by dividing total earnings by total times as:
[tex]\text{Amy's hourly earnings}=\frac{\$120}{12}[/tex]
[tex]\text{Amy's hourly earnings}=\$10[/tex]
Therefore, Amy earns $10 per hour.
We can see that $10 are $0.25 more than $9.75, therefore, Amy earns $0.25 more than John.
