Write a function that models the time the sun sets as a function of the week #, where June 1 is Week 1.
What time should Eliana predict the sunset to take place during the first week of March (week 41)?
One possibility is to use cosine.
Find the variables for y = acosb(x − c) + d.
Substitute x = 41 into the answer from part (a).
