Last week, a man worked 47 hours at Starbucks. Find his gross earnings for the week if he is paid $7.80 per hour and earns time-and-a-half for all hours over 40.

Step 1: Calculate regular time pay up to 40 hours:
Regular Pay = Hourly Wage * Hours up to 40
Regular Pay = $7.80 * 40
Regular Pay = $312

Step 2: Calculate overtime hours above 40 hours:
Overtime Hours = Hours Worked - 40 hours
Overtime Hours = 47 - 40
Overtime Hours = 7

Step 3: Calculate overtime pay above 40 hours:
Overtime Pay = 1.5 * Hourly Rate * Overtime Hours
Overtime Pay = 1.5 * $7.80 * 7
Overtime Pay = $81.90

Step 4: Calculate Gross Earnings
Gross Earnings = Regular Pay + Overtime Pay
Gross Earnings = $312 + $81.90 = $393.90
