Question

You have $300. Your sister has at most $50 less than you. Write an inequality that matches the situation. Give an amount of money your sister could have.

Answer 1

At most 50 less than you. You have 300
So 300-50 =250 thats the best scenario, because 50 is most that can be subtracted. (Example, Instead of 50 it can be 40 but not 60. If 40, it becomes 260 so more than if subtracted by 50.)
So,
X>= 250
