Question

Beth has $300 in her bank account. She buys x shirts for $20 each.

Answer 1

300-20x less than our equal to 100

Answer 2

300-100 to make sure that she still has the $100 saved and Beth will have $200 to spend on shirts.
200/20 is 10 So Beth can buy 10 shirts for $20 dollars each with 100 dollars still left in her account. I HOPE THIS HELPS!!!
