Gretchen works at a department store. She earns a 12% commission
on the perfume that she sells and a 6% commission on the clothes
that she sells. Gretchen sells $350 worth of perfume and $700 worth of clothes
in one day. What is her commission that day?
Total Commission = Commission for Perfume + Commission for clothes =12% of sales + 6% of sales =12% of 350 + 6% of 700 =(350x12/100)+(700x6/100) =(4200/100)+(4200/100) =42+42 =$84
