To find the customer’s bill, we can set up the equation based on the information given.

Let \( x \) be the total bill. According to the problem, the tip of $1.00 represents 22% of her bill. This can be expressed as:

\[ 0.22x = 1.00 \]

To solve for \( x \), divide both sides by 0.22:

\[ x = \frac{1.00}{0.22} \approx 4.5454545454545 \]

Rounding to the nearest cent, the customer’s bill is approximately:

\[ x \approx 4.55 \]

So, the customer’s bill was $4.55.
