Kendra wears 1 * 5 = <<1*5=5>>5 shirts for school days.
She wears 1 * 3 = <<1*3=3>>3 extra shirts for her after-school club.
She wears 1 + 1 = <<1+1=2>>2 shirts on Sunday.
With her shirt on Saturday, she wears 5 + 3 + 1 + 2 = <<5+3+1+2=11>>11 shirts each week.
She wants to have 2 weeks’ worth of shirts, so she needs 11 * 2 = <<11*2=22>>22 shirts.
