Emerson is making a punch that contains 60% grape juice and the rest lemon-lime soda. the punch has 2 liters of lemon-lime soda. part a: write an equation using one variable that can be used to find the total number of liters of grape juice and lemon-lime soda in the punch. define the variable used in the equation and solve the equation. hint: 0.6x represents the number of liters of grape juice in the punch. part b: how many liters of grape juice are present in the punch? show your work.

A. 0.4x=2, x=5 liters

B. 3 liters

Step-by-step explanation:

Part A. Let x liters be the total number of liters of grape juice and lemon-lime soda in the punch. If punch contains 60% grape juice, then the amount of grape juice is 0.6x liters and the amount of lemon-soda is

x-0.6x=0.4x liters.

The punch has 2 liters of lemon-lime soda, thus,

0.4x=2.

Multiply this equation by 10:

Part B. Since the punch contain 2 liters of lemon-soda, then the punch contains

5 - 2 =3 liters of grape juice.

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
