Question

Sierra left $4.50 as a tip for a waiter. This was 18% of the bill before the tip. How much was her total bill before the tip?

Answer 1

Answer:

The total bill before the tip would be $ 25

Step-by-step explanation:

Let x be the amount of total bill,

∵ tip is 18% of the bill,

So, the amount of bill = 18% of x = 0.18x,

According to the question,

0.18x = 4.50

$\implies x =\frac{4.5}{0.18}=25$

Hence, the total bill before the tip would be $ 25.

Answer 2

Answer:

Total amount of bill is $25.

Step-by-step explanation:

Given information:

The amount of tip = $4.50

The percentage given = 18%

Let total amount is $x$

As the tip is 18% of the total bill;

Then,

We can write:

$0.18 \times x=4.50$

$x=4.50/.018$

$x=25$

Total amount of bill is $25.
