# Cost Of Owning a Car Problem Storyboard

#### Storyboard Text

• I really like the car we looked at. My decision will come down to the distance to cost ratio.﻿
• The what?﻿
• You know, how far the car can go while costing me a certain amount of money.﻿
• Oh I get it. Come with me, I'll look it up.﻿
• Ok I'll think about it and be back with my decision tomorrow.﻿
• ﻿The computer says that car can is about \$366 for 300 km and \$510 for 1500km.
• Hmm let me think. What he gave me was two points. That means I can tell how much money it will take me to go on my trip. I estimated about 2000km for a round trip.﻿
• If the two points he gave me were (300,366), and ﻿﻿(1500,510), that means that my slope is 3/25 and my y-intercept is 330. Now if I make an equation it would be, Y=3/25x+330. Now if I fill in my data. That's a reasonable price.
• I did the math yesterday and found out that it would cost me about \$570 for my 2000km trip. I'll take the car.﻿
• ﻿Great! Let's go take car of some paperwork.
