Choose the method of pay that would result in the most earnings for one month on sales of $60,000.

a. straight commission of 6% on all sales.

b. monthly salary of $1,500 plus 3% commission on all sales

c. graduated commission 4% on the first $50,000 in sales and 10% on anything over that.

d. graduated commission of 5% on the first $40,000 in sales on 9% on anything over that.

To solve: first go down the line and find the total amount that would be made for each scenario to then decide which option is best

Straight commission of 6% on all sales.

(60,000)(0.06) = $3,600

B. Monthly salary of $1,500 plus 3% commission on all sales

$1,500 + (60,000 x 0.03) = x

$1,500 + $1,800 = $3,300

C. Graduated commission 4% on the first $50,000 in sales and 10% on anything over that.

($50,000 x 0.04) = $2,000

($10,000 x 0.10) = $1,000

add the two of these up = $3,000

D. Graduated commission of 5% on the first $40,000 in sales on 9% on anything over that.

($40,000 x 0.05) = $2,000

($20,000 x 0.09) = $1,800

add the two of these up = $3,800

$3,800 is the greatest total amount so option D would be the best bet.
