The homework for Holiday Break is hard and fun at the same time. I finally figured out that you can not find the answer without manipulating the data that was given. I kept trying to use 12,000 miles per year, 39 and 25 MPG, and $2.75 per gallon together; Then many erasers and "SYNTAX ERRORS" later finally divided 12,000 by the MPG (25 or 39)... this gave the gallons needed to travel 12,000 miles. This also did not work. I looked at my table and for different values of X(years of ownership) the Y(cost) values were all the same. So then I realized that 12000 miles per year had to be multiplied by the number of years X to see a chance in the cost per year. Finally my table and graph looked good! Did it take anyone else many tries to get the answer as it did me? Did anyone else have trouble finding y=equations to put into their calculator? and Does my equation look right... A=20000+((12000*X)/25)*2.75 B=25000+((12000*X)/39)*2.75

Yes, my equation looked similar to yours, but with out all the parentheses. I did not include them because of order of operations.
