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.
