Problem
To train for a race, Michele jogged 6 miles each day before the last two days before the race. She jogged 10 miles each of those two days. Write an expression to represent the number of miles that Michele jogged in preparation for the race. Let d represent the number of days T PR
Solution
For this case we can use T as the total miles in practice and we can do this:
T= 6x +10 y
Where x= number of days (before 2 days before the race)
y= last two days
