19. (3 pts) sammy works in an electronics store. sammy earns $225 per week, plus a 25% commission on each electronic sold. how much would sammy earn if he sold $640 worth of electronics in one week?

Answer

Explanation:

Step1: Calculate the commission amount

The commission rate is 25% or 0.25, and the value of electronics sold is $640. The commission amount $C$ is calculated by multiplying the rate by the value of sales. So $C = 0.25\times640$. $C=0.25\times640 = 160$

Step2: Calculate the total earnings

Sammy has a base - pay of $225 per week. The total earnings $E$ is the sum of the base - pay and the commission. So $E=225 + C$. $E=225+160=385$

Answer:

$385$
