algebra 2 word problem

Give each month a number:

January = 0

February = 1

March = 2

April = 3

Now set X to 3 in the equation ad solve for t.

t = -30cos(x/6) +60

t = -30cos(3/6) +60

t = 33.672 degrees. ( Round as necessary)

You would need to change the +60 to a new starting point based on what the rise in temperature is due to global warming.
