The number of guests they have can be approximately modeled by the function G(d)=235cos( 0.03443 (d+12) )+315, where G is the approximate number of guests on the dth day of the year. If the resort considers their peak season to be when they have 85% or more of their max number of guests, approximately when is their peak season? Choose all correct answers.
