Question

The Andersons went to dinner at the Louisiana Seafood. If their dinner cost $36.90 and they left a 15% tip for their server, how much did they pay their server for tip?

Answer 1

$4.81

Step-by-step explanation

you can easily solve this by using a rule of three.

Step 1

let

the dinner cost $36.90 , this is the value of the food plus the 15% for tip

then, 36.9 is the 115 %

if

`36.9\rightarrow115`

then how much is the 15%

Let

x= $ of the tip

then

`x\rightarrow15`

Step 2

make the relation and solve for x

`\begin{gathered} (36.9)/(115)=(x)/(15) \\ \text{multiply both sides by 15} \\ (36.9)/(115)\cdot15=(x)/(15)\cdot15 \\ x=(553.5)/(115) \\ x=4.81 \end{gathered}`
