You start out with d dollars. You spend 22 dollars. So you now have d - 22 dollars left

But since you know for certain that you have "at least 28 left", this means that the quantity d - 22 is greater than or equal to 28. So we know that

d-22%3E=28

Now let's solve for 'd'


d-22%3E=28 Start with the given inequality.


d%3E=28%2B22 Add 22 to both sides.


d%3E=50 Combine like terms on the right side.

Answer:

So the solution is d%3E=50


This means that you had at least $50 in the account initially.
