A customer put $1.00 in the tip jar at a coffee shop. This amount represented 22% of her bill.

Question

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.
