PLEASE HELP ASAP!!!
Makaila would like to walk at least 70 blocks over the next five days. She would like to increase the number of blocks she walks by two per day for each of the second and third days. Then, she wishes to level off so that the fourth and fifth days she walks only as far as she did on the third day.


a. If the amount that Makaila walks the first day is represented by x, then write expressions for each distance she walks the other four days.
Day 1= x Day 2 = Day 3 = Day 4 = Day 5 =

b. Find all possible values that Makaila could walk on the first day to reach her goal.

c. Assuming that Makaila walks a whole number of blocks on Day 1, what is the fewest number of blocks she could walk on this day and still meet her goal.
