Alice earned $500 per week. what equation shows the relationship between her total amount earned (t), number of weeks (n), and rate per week (r).

Step-by-step explanation:

Let n represent the number of weeks, t represents the total amount earned and r represent the rate per week.

As total amount will be equal to number of weeks times rate per week, so we can represent this information in an equation as:

We have been given that Alice earns $500 per week. This means that rate per week is $500.

As n represents the number of weeks, so amount earned in n weeks will be 500n.

So the total amount earned in n weeks will be 500n. We can represent this information in an equation as:

Therefore, the equation represents the relation between total amount earned (t) in n, number of weeks, and rate per week (r).

the answer is 62.8 cubic units
