Ka Mosupologo o ruta diklase di le 4 ka diura di le 5, mme ka Laboraro a rute diklase di le 2 ka diura di le 2.  Ke bokae bo Tanya a bo amogetseng mo malatsing a mabedi a a rutileng?

To make 1 liter of juice, Sam needs 5 kilograms of oranges. Each kilogram of oranges costs $3. How much money would Sam have to spend to make 4 liters of juice?
Tanya o berekile diura di le 5 + 2 hours = <<5+2=7>>7 diura.
Ka jalo o amogetse  7 diura * R15/ura = R<<7*15=105>>105.
Ka Mosupologo o rutile diklase tse di fetang 3, ka jalo o bone bonase mme ka kakaretso a amogela R105 + R5 = R110. 
#### 110 

To make 4 liters of juice, Sam needs 4 * 5 = <<4*5=20>>20 kilograms of oranges.
If one kilogram of oranges costs $3, then 20 kilograms would cost 20 * 3 = $<<20*3=60>>60.
