2. Homework Equations

2. Homework Equations

y=mx + b

## The Attempt at a Solution

**a.***y*= –65*x*+ 200To stay at a private golf course, you have to pay a total of $2500. But, the private golf course has a deal that says if you purchase a membership for the golf course, which costs $200, $65 of the total cost will be deducted per day. In the equation, y represents the total cost, -65 represents the discount of the member ship (a $65 deduction), x represents the number of days spent at the golf course after purchasing the membership, and $200 is the total cost of the membership.

**b.***y*= 3.5*x*+ 10A local car wash charges a total of $3.5 per car wash, with an additional fee for extra services. In the equations above, y represents the total cost of the car wash, 3.5 represents the total cost per car wash, x represents the number of car washes, and 10 represent the additional fee for extra services.

I understand what I have to do and I know I'm doing it correctly, just wanted to know if the 2 examples I gave for each line made sense. Since it has to be realistic I can't have a scenario that doesn't sound realistic.
