C 2x + 15 = 5

Respuesta :

Answer:

A 0.2(x + 15) = 5

Step-by-step explanation:

Let x represent the cost of Ramesh's dinner.

Since, Pilar's dinner cost $15.

The sum of pilar and Ramesh's dinner is;

= 15 + x

And also, since the tip is 20% of the cost of their dinner;

tip = 20% of (15+x) = 0.20(15+x)

The amount of the tip is equal to $5

0.20(15+x) = 5

Which gives;

0.2(x+15) = 5

Solving the equation, we have;

x+15 = 5/0.2

x+15 = 25

x = 25-15

x = $10
