Candy bars cost $2 each at the concession stand. in the equation below, x represents the total number of candy bars sold, and y represents the total revenue made selling candy bars. the relationship between these two variables is modeled by the equation y = 2x.

what is the dependent variable?

a) the value of 2 in the equation.
b) the total number of candy bars sold.
c) the total revenue made selling candy bars.
d) it cannot be determined from the given information.

C) The total revenue made selling candy bars.

Step-by-step explanation:

A dependent variable is one whose values depends on another variable. In y = 2x, the value of the variable y depends on x; therefore, y is the dependent variable. And since y is the total revenue made selling candy bars, the total revenue made selling candy bars is the dependent variable, which is choice C.

Also,  x is an independent variable, because its value does not dependent on anything—we are free to choose whichever value of x we like.

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
