Kendra wants enough shirts that she only has to do laundry once every two weeks. She wears one shirt to school for each of the five weekdays. Three days a week, she changes into a different shirt for an after-school club. On Saturday, she wears one shirt all day. On Sunday, she wears a different shirt to church than she does for the rest of the day. How many shirts does she need to be able to only do laundry once every two weeks?
##Solution## 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.
