they agree to share the cost of pizza based on the portion they ate. she ate 2/3 of his portion. what does the equation look like
To determine the equation of how to share the cost of pizza based on the portions eaten, we can start by assigning variables. Let's call the total cost of the pizza "C," and the portions they ate "x" and "y," respectively.
Since she ate 2/3 of his portion, we can express her portion as 2/3(y). It can be implied that his portion is y. Thus, the equation can be written as:
C = x + y + 2/3 y
In this equation, "x + y" represents the total portion of pizza eaten, and "2/3 y" represents the specific share eaten by her.
To calculate the cost of the pizza, you need to know the values of x and y, as well as the total cost of the pizza. With these values, you can substitute them into the equation and solve for C.
