Emil o na le dingwaga di le 19 jaanong. Fa a tla bo a na le dingwaga di le 24, o tla bo a le halofo ya dingwaga tsa ga rraagwe mme a le gabedi ya dingwaga tsa ga morwarraagwe. Ke palobatlhogo efe ya dingwaga tsa ga rraagwe le morwarraagwe jaanong? 

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?
Rraagwe o tla bo a na le dingwaga di le 24 x 2 = <<24*2=48>>48 fa Emil a na le dingwaga di le 24.
Morwarraagwe o tla bo a na le dingwaga di le 24 / 2 = <<24/2=12>>12 ka nako eo.
Emil o tla nna dingwaga di le 24 mo dingwageng di le 24 - 19 = <<24-19=5>>5.
Dingwaga tsa ga rraagwe jaanong ke 48 - 5= <<48-5=43>>43.
Morwarraagwe o na le dingwaga di le  12 - 5 = <<12-5=7>>7 jaanong.
Palobatlhogo ya dingwaga tsa ga rraagwe le morwarraagwe jaanong ke 43 + 7 = <<43+7=50>>50.
#### 50

She will be outside 4 hours a day for 8 days so that's 4*8 = <<4*8=32>>32 hours
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
Her bottle holds 8 ounces of sunscreen and she needs 32 ounces so she will need to pack 32/8 = 4 bottles of sunscreen
