Mixed number is the sum of a whole number and a fraction.
We need to find the mixed number between 0 and 2, the smallest mixed number should be greater than 1(between 0 and 2). Because if we add a fraction to 0 it will gives us that fraction, not a mixed number.
We want to use the interval of 1/3 between each pair of mixed numbers;
Y=.25x+176.10 Y is the monthly cost and B would be the cost of the insurance every month. X is the amount of miles driven since the .25 stays constant but the amount of miles you drive in a month is different every month, Hence, needs to be a variable that can be adjusted,
