Ms. Tompkins had an amount of money in the bank. After she deposited $100, she had at least $550 in the bank. how much money did Ms. Tompkins have in the bank originally? i need explanation pls , ty

at least $450

Step-by-step explanation:

Let the amount she has in bank before depositing be x

If she had at least $550 in the bank after depositing, then;

x + 100 ≥ 550

Get the initial amount in bank

x ≥ 550 - 100

x ≥ 450

Hence the amount she has in the bank originally was at least $450
