Question

Tomas is leaving a tip of 18% of his original bill. If the amount of the tip is $2.34, which of the following equations can be used to find the amount of his original bill?0.18b = 2.34b - 0.18 = 2.342.34 x 0.18 = bb/2.34 = 0.18

Answer 1

0.18b = 2.34

Explanation

Let's call b to the bill

The tip is 18% of the bill. To find the 18 percent of a number, we need to multiply this number by 18 and then divide by 100. In this case, the tip is:

`\begin{gathered} tip=(18)/(100)b \\ tip=0.18b \end{gathered}`

The amount of the tip is $2.34, then:

`0.18b=2.34`
