This is because it has a higher mpg capacity, so they will drive around the city more, for a lower price. 2) I would let Cody drive the SUV, as the hybrid will be newer, and Cody is a beginner and is not as experienced, and so he is likely to crash the hybrid which will cost more money to repair. Part 2 Car Distance(miles ) Mpg Gallons of gas to go 100miles Cost (in $) to go 100 miles SUV 100 13 7.69 30.77 Minivan 100 17 5.88 23.53 Corolla 100 28 3.57 14.29 Hybrid 100 48 2.08 8.33 2) Car combination Total cost of driving 100 miles SUV-Corolla 45.06 Minivan-Corolla 37.82 SUV-Hybrid 39.10 Minivan-Hybrid 31.86 a) The most expensive combination is the SUV-corolla b) The most economical combination is the Minivan-Hybrid c) The total cost is $45.06 cost to drive 100 miles before trade cost to drive 100 miles after trade savings SUV & Corolla= $45.06 Minivan & Corolla=$37.82 $ 7.24 SUV & Corolla= $45.06 SUV & Hybrid= $39.10 $ 5.96 d) Trading the SUV and Corolla for the minivan and corolla would save the family the most money. 3a) the calculations disprove my hypothesis. I did not conduct any calculations, and assumed that trading the corolla with the hybrid will grant the family an additional 20mpg, while trading the SUV for the minivan will grant them an additional 4mpg only. b) no, they did not make the right decision, they are spending $1.28 more than the maximum amount of savings they could have had, which is $5.96 c) 5.96/4= 1.49 gallons d) 1.49*13= 19.37 miles
