Answer 1

Answer:

$300+40w>700$

Step-by-step explanation:

Bobby's uncle gave him 300 baseball cards. Each week, Bobby purchases 40 baseball cards to add to his collection.

Let the number of weeks he collects cards be w.

The inequality to get the number of weeks after starting his collection when Bobby will have more than 700 baseball cards in his collection is given by:

$300+40w>700$

If you want to find w;

$40w>700-300$

=> $40w>400$

w > 10

Answer 2

Answer:

He already has 300 cards.

Take 700 and subtract that by 300

Then divide that by 40

Leaves you at

10 weeks
