Delia works from 8:00 a.m. to 4:30 p.m. and has one hour each day for lunch. How much does she earn for a fiveday workweek at $4.80 per hour?

From 8am to 4:30pm, there are 8 hours and 30 minutes. Subtract one hour for lunch, she worked (was paid) 7.5 hours per day.
Over 5 days, she worked 5*7.5=37.5 hours.
At $4.80 and hour, she makes $4.80*37.5=?
