at the fancy restaurants the cost to income ration is 3:20. if a special meal cost the chef 9 dollar to prepare cost what should the chef charge customers for the meal income

Respuesta :

The chef should charge the customers $60 for the meal income

Here, we want to get the cost the meal should be for customers

We are going to use a proportion in this case

Let the cost of the meal to customers be $x

We have to equate the ratio to the cost to income ratio

We have this as follows;

[tex]\begin{gathered} 3\colon20\text{ = 9:x} \\ \frac{3}{20}\text{ = }\frac{9}{x} \\ \\ 3\text{ }\times\text{ x = 9}\times20 \\ 3x\text{ = 180} \\ x\text{ = }\frac{180}{3} \\ \\ x\text{ = \$60} \end{gathered}[/tex]
