i need explanation pls , ty

Answer 1

at least $450

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
