Sagot :

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.
