Justin earns $8 an hour for the first 40 hours he works and $12 for each additional hour. How much will justin earn for a week in which he worked 48 hours

Step-by-step explanation:

Let x represent the number of hours that Justin works in a week.

Let y represent the total amount that Justin would receive for working for x hours.

Justin earns $8 an hour for the first 40 hours he works and $12 for each additional hour. This means that the total amount that he earns in a week would be

y = 8*40 + 12 (x - 40)

y = 320 + 12 (x - 40)

If he earns 48 hours in a week, the total amount that he earned would be

320 + 12 (48 - 40) = $416
