The following equations represent walkathon pledge plans (for money earned after miles walked). Explain each pledge plan in terms of rate and starting point:
y = 4x; y = 2x + 6; y = 10
What is
y = 4x --> You get $4 for every mile walked;
y = 2x + 6 --> You get $6 for participating and $2 for each mile walked;
y = 10 --> You get $10 no matter how many miles you walk

Molly is planning a skating party and she has to choose between two different companies. Option 1 charges a flat fee of $10 and $3 for every pair of skates rented. Option 2 charges $5 for every pair of skates rented.
Write an equation that represents the cost plan for each option. Make sure to define your variables.
What is y = cost; x = # skates rented
Option 1: y = 3x + 10
Option 2: y = 5x
