Ответ:
$4x+$360=$10x+$6x
Combine like terms.
$4x+$360=$16x
Subtract $4x on both sides to balance out the equation.
$12x=$360
Divide by $12.00 on each side.
x=30 visits
To check your work, plug in what x equals or 30 in the original equation. If you come up with a true statement, then you know your answer has to be correct.
4x+360=16x
4(30)+360=16(30)
120+360=480
480=480
Because this is a true statement, you can be certain that the total number of visits when the cost of a member and a nonmember will be the same is 30 visits. Hope I helped! Brainliest too please.
