### Instruction:
Phoebe eats 1 serving and gives her dog 1 serving of peanut butter for a bedtime snack. Each jar of peanut butter has 15 servings.  How many jars will she need to make sure she and her dog have enough to last for 30 days?

### Response:
 Kwa siku 30, Phoebe na mbwa wake wote hula kipande kabla ya kulala hivyo ni 30*2 = <<30*2=60>>60 vipande
Kila chupa ina vipande 15 na anahitaji vipande 60 kudumu kwa siku 30 hivyo ni 60/15 = <<60/15=4>>4 za siagi ya karanga
