Kris: y = 1.5k + 5
John: y = 1k + 6
solve 1.5k+5 = k+6
Kris is starting a delivery business in Ottawa called Kris' Speedy Express. He charges $5, plus $1.50/kg to deliver a package throughout all of Ottawa including all outside communities. His competition, John's Same Day Deliveries charges $6 per delivery plus $1.00/kg. When is it less expensive to use John's Same Day Deliveries?
Can someone help me with the starting equations?
