The earnings of two employees are given below:
employees a: 6% commission on all sales.
employee b: 4% commission on the first $80,000 and 8% on anything over $80,000.
how much more does a straight commission employee make then the graduated commission employee for sale of $100,000?
a.$1,200
b.$1,600
c.$2,000
d.$3,200

The answer is a. $1,200. Employee A has 6% commission on all sales. For sale of $100,000 which is 100%, x is the commission of 6%. $100,000 : 100% = x : 6%. x = $100,000 * 6% : 100% = $6,000. Employee B has 4% commission on the first $80,000 and 8% on anything over $80,000. For sale of $80,000 which is 100%, x is the commission of 4%. $80,000 : 100% = x : 4%. x = $80,000 * 4% : 100% = $3,200. For sale of $20,000 which is 100%, x is the commission of 8%. $20,000 : 100% = x : 8%. x = $20,000 * 8% : 100% = $1,600. The total commission for Employee B is $3,200 + $1,600 = $4,800. The difference between Employees A and B is: $6,000 - $4,800 = $1,200.
