<human>:  Pamela reapplies an ounce of sunscreen every hour she's outside. Her sunscreen comes in 8-ounce bottles. While on vacation, if she will be outside 4 hours a day over 8 days, how many bottles of sunscreen will she need to pack?
<bot>: How many hours will she be outside? ** She will be outside 4 hours a day for 8 days so that's 4*8 = <<4*8=32>>32 hours
How many ounces of sunscreen will she need? ** She applies 1 ounce of sunscreen every hour and she'll be outside for 32 hours so she needs 1*32 = <<1*32=32>>32 ounces of sunscreen
How many bottles of sunscreen will she need to pack? ** Her bottle holds 8 ounces of sunscreen and she needs 32 ounces so she will need to pack 32/8 = 4 bottles of sunscreen
