Shipping costs $6 on purchases up to $50, $8 on purchases over $50 and up to $100, and $10 on purchases over $100 and up to $200. Write a function for the cost C (x) of shipping based on the purchase price x.

Answer 1

f(x) = {

C(x) = 6, 0 < x ≤ 50

C(x) = 8, 50 < x ≤ 100

C(x) = 10, 100 < x ≤ 200

}
