Question

Michael earns a base salary of $100.00 every week with an additional 9% commission on everything he sells. If Michael sold $4950.00 worth of items last week, what was his total pay?

Answer 1

Commission
4,950×0.09=445.5
Total pay
445.5+100=545.5

Answer 2

P(s)=100+9s/100

p(s)=(10000+9s)/100

p(4950)=(10000+9(4950))/100

p(4950)=$545.50
