Answer:

Se pagará $7200.

Step-by-step explanation:

La ecuación del costo puede descomponerse en dos factores que luego se multiplican:

1) Siendo A el area del del muro, la parte del costo que depende del área se calcula como un tercio (1/3) del doble (2) del área A. Este factor se puede escribir como:

C_1=(1/3)\cdot 2 \cdot A=(2/3)\cdot A

2) Siendo T el número de trabajadores, el siguiente factor es el triple del numero de trabajadores T. Esto es:

C_2=3T

Multiplicando ambos factores, tenemos la ecuacion del costo en función de A y T:

C=C_1\cdot C_2=(2/3)A\cdot 3T=2 AT

Si se planea pintar un muro de 1200m² y se contrataran a 3 trabajadores, el costo será:

C=2AT=2(1200)(3)=7200
