b. monthly salary of $1,500 plus 3% commission on all sales.
c. graduated commission of 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 and 9% on anything over that.

Explanation:

Step1: Calcular ganancias para a

La comisión única es del 6% de $60,000.
$0.06\times60000 = 3600$

Step2: Calcular ganancias para b

El salario mensual es de $1500$ más una comisión del 3% de $60,000$.
$1500+0.03\times60000=1500 + 1800=3300$

Step3: Calcular ganancias para c

Comisión del 4% en los primeros $50000$ y 10% en el excedente.
$0.04\times50000+0.1\times(60000 - 50000)=2000+1000 = 3000$

Step4: Calcular ganancias para d

Comisión del 5% en los primeros $40000$ y 9% en el excedente.
$0.05\times40000+0.09\times(60000 - 40000)=2000 + 1800=3800$

Answer:

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