Bobby's uncle gave him 300 basketball cards each week Bobby purchased 40 basketball cards to add to his collection which i n e q u a l i t y 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
Let's call the number of weeks after starting his collection as "w".
Each week, Bobby's uncle gives him 300 basketball cards.
Therefore, in w weeks, Bobby will have received 300w basketball cards from his uncle.
Each week, Bobby also purchases 40 basketball cards to add to his collection.
Therefore, in w weeks, Bobby will have purchased 40w basketball cards.
To find the total number of basketball cards in Bobby's collection after w weeks, we can use the inequality:
300w + 40w > 700.
Simplifying the inequality, we get:
340w > 700.
Dividing both sides of the inequality by 340, we get:
w > 700/340.
Performing the division, we get:
w > 2.06.
Since we cannot have a fraction of a week, we can conclude that Bobby will have more than 700 basketball cards in his collection after 3 or more weeks.
