Question

A customer put $1.00 in the tip jar at a coffee shop. This amount represented 22% of her bill.
How much was the customer’s bill? Round your answer to the nearest cent.


$22.00

$4.55

$1.22

$2.20

Answer 1

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**.
