Aused-car costs $5,000. you figure you can get 4 years out of it. you drive 10,000 miles per year. your car insurance costs $1,200 per year. you figure you'll spend $400 per year on maintenance. gas costs $3 per gallon, and the car gets 25 miles per gallon. what will your average cost (all costs included) per mile be over the 4 years?

To start it is $5000 then $1200 for insurance, $400 for maintenance, and gas is 10,000 miles per year with 25 miles per gallon. So 10,000 divided by 25 equals 400, now 400 is the gallons and each gallon in $3. 400 times 3 is 1200, now with the numbers you have the formula of 4(1200+1200+400)+5000 do that and you get the answer of $16,200 for the four years.

No a triangle cannot be formed because when you add the two smallest number together (which would be 11) the have to be bigger than the number it is "against" ( which would be 12)

Need the graph to answer this.
