Question

Adam is a salesperson in a video store. He is paid $100 every week plus a commission of $5 on every DVD he sells. Which equation can be used to find out how many DVDs, x, he sold in a week, if he earned $150?

Answer 1

Answer:

X = (150 - 100) / 5

Step-by-step explanation:

To determine how many DVDs Adam sold in the week, knowing that he charges a fixed amount of $ 100 plus $ 5 for each sale he makes, and in the week he charges a total of $ 150, the following calculation must be made:

X (number of DVDs sold) = (150 (weekly profit) - 100 (fixed amount)) / 5 (value of each DVD)

X = (150 - 100) / 5

X = 50/5

X = 10

So, during the week Adam sold 10 DVDs.
