The more of his coworkers who attend the picnic, the more veggie burgers he will prepare. Which of the variables is independent and which is dependent?

The dependent variable is burgers and independent variable is coworkers.

Step-by-step explanation:

Given: The more of his coworkers who attend the picnic, the more veggie burgers he will prepare.

To find: dependent and independent variables

Solution:

The value of the independent variable remains unaffected with changes in other variables.

The value of the dependent variable depends on the value of the independent variable.

Here,

The dependent variable is burgers and the independent variable is coworkers.

(number of burgers depend on the number of coworkers)

thats not a system of equations, that is a solution

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
