Bobby’s uncle gave him 300 baseball cards. Each week, Bobby purchases 40 baseball cards to add to his collection.
Which inequality can be used to find w, the number of weeks after starting his collection when Bobby will have more than 700 baseball cards in his collection?
A) 300w + 40 > 700
B) 300w + 40 < 700
C) 40w + 300 > 700
D) 40w + 300 < 700
To find the inequality that represents the relationship between the number of weeks (w) and the number of baseball cards Bobby will have in his collection, we need to consider the given information.
Bobby starts with 300 baseball cards given to him by his uncle. Each week, he purchases 40 additional baseball cards.
So, the number of baseball cards Bobby will have after w weeks can be represented as:
Number of baseball cards = 300 + 40w
To find the inequality that represents when Bobby will have more than 700 baseball cards, we can set up the following inequality:
300 + 40w > 700
This inequality states that the total number of baseball cards (300 + 40w) should be greater than 700.
Therefore, the correct answer is option A) 300w + 40 > 700.
clearly not B or D, since you want "more than" 700
So, what do you think? He started with 300, so ...
