Answer: 195 = 35x + 20
Step-by-step explanation: This follows the y = mx + b formula.
y is your total, what the equation equals, and in this case it is your total cost of $195.
x is your independent variable, and time is always independent. When m is $35, you can plug in any hour (time!) for the x.
b is your initial value. This is what you start with, and in this case, it is your $20 equipment fee. You KNOW you have to pay that.
Hope this helps!
