21. (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. The value of electronics sold is $640. So the commission amount is the product of the rate and the value of sales. $0.25\times640 = 160$

Step2: Calculate the total earnings

Sammy has a base - pay of $225 per week. Add the commission amount to the base - pay. $225 + 160=385$

Answer:

$385$
