FUNCTION NOTATION PLEASE!! By noon, a charity had collected 83 shirts. Every hour after that, it collected 20 more shirts.

Function s gives the number of shirts the charity had collected as a function of the
number of hours.

a. Use function notation to write a rule that defines function s. Create a table, if needed.
b. Find w for s(h) = 167 and explain what this value of w means in this situation.
