25. In Mrs. Stout’s class students are hoarding eraser caps. Olivia and Mackenzie are afraid that they will not have erasers to fix their mistakes on the EOC. Olivia started out with 7 erasers and is now hoarding 5 additional erasers per day. Mackenzie started out with 3 erasers and is now hoarding 7 additional erasers per day.

a.  Write a function o(x) to represent the number of erasers that Olivia has hoarded.

b.  Write a function m(x) to represent the number of erasers that Mackenzie has hoarded.

c.  Combine the two functions into one function to show the total number of erasers hoarded s(x) = o(x) + m(x)

d.  Calculate the total number of erasers they have hoarded after 4 days, three weeks, and 45 days.

4 days: ______three weeks: ______45 days:______
