James earns $8.15 per hour.
We are asked to find out which algebraic equation shows the amount of money that James earns in n hours.
Let n represents the number of hours that James work
Since James earns $8.15 for working one hour then we can write
[tex]E=8.15n[/tex]Where E represents the earnings.
n represents the number of hours.
For example:
If James work for 5 hours then he will earn
[tex]\begin{gathered} E=8.15n \\ E=8.15(5) \\ E=40.75 \end{gathered}[/tex]As you can see, you just have to substitute the number of hours (n) to get the earnings.
Therefore, the correct option is d.
