If Ming earned $157.50 for working 30 hours, his hourly rate can be found by dividing his total earnings by the number of hours worked:
Hourly rate = Total earnings / Number of hours worked
Hourly rate = $157.50 / 30 hours
Hourly rate = $5.25 per hour
To find how much Ming will earn for working 35 hours the next week, we can multiply his hourly rate by the number of hours worked:
Earnings = Hourly rate x Number of hours worked
Earnings = $5.25 per hour x 35 hours
Earnings = $183.75
Therefore, Ming will earn $183.75 for working 35 hours the next week.
