Type A: f(x)= 10 + 8x Type B: g(x)= 17 + 7x Two types of generators each require a fixed amount of fuel to start. After starting, each generator produces a constant amount of energy per ounce of fuel used. The functions fand g above represent the amount of fuel, in ounces, that each type of generator requires to produce x units of energy when started once. 29 A type A generator was used to produce units of energy, and a type B generator was used to produce k units of energy. Each generator-was started once, and a combined total of 100 ounces of fuel was used. Which of the following equations represents the relationship between n and k? A) 8n+7k 100 B) 8m+7k-73 C) 8n+7k=127 8n 7k D) +7 100 100 30 A type A and a type B generator were started and operated until they ran out of fuel. The two generators combined used 216 ounces of fuel to produce 25 units of energy. How many more units of energy were produced by the type A generator than by the type B generator? A) 0.2 B) 3.0 C) 11.0 D) 12.6
