1.) Total hours worked for the week :
(6.25 + 7.25 + 6.00 + 6.75 + 5.00) = 31.25 hours
2.) Total amount earned for the week :
(total hours worked × earning per hour)
(31.25 × 10.25) = $320.3125
3.)
Weekly salary = $150
Commission on sale = $0.25 per ice cream sold
Average sale on number of ice cream per week = 125
Total amount made on ice cream sale :
Weekly salary + (average weekly unit sold × commission per sale)
$150 + (125 × $0.25)
$150 + $31.25 = $181.25
Amount made per week in old position > earning per week in New position
