Acollege cafeteria pays student cashiers $10.20 per hour. cashiers earn an additional $1.30 per hour for each hour worked over 35 hours per week. a cashier worked 40 hours one week and 38 hours the second week. how much did this cashier earn in this two-week period?

$806

Step-by-step explanation:

The regular earning of a cashier = $10.20 per hour

over 35 hours per week he gets = $10.20 + $1.30 per hour

                                                      = $11.50 per hour

He worked 40 hours in first week and 38 hours the second week.

His earnings in first week  = (35 × 10.20) + (5 × 11.50)

                                           = $357 + $57.5

                                           = $414.50

His earnings in second week = (35 × 10.20) + (3 × 11.50)

                                                 = $357 + $34.50

                                                 = $391.50

His total earnings in this two weeks = $391.50 + $414.50

                                                            = $806

His total earning was $806.
