Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Blake bought 4  lollipops and 6 packs of chocolate. If each lollipop costs $2 and a pack of chocolate costs the same as four lollipops, how much change will Blake get back if he gave the cashier 6 $10 bills?

### Response:
 Blake alinunua vitu 10.
Jumla ya gharama ni 10 x $2 = $<<10*2=20>>20.
Blake alitoa $10 x 6 = $<<10*6=60>>60.
Hivyo, Blake atapata $60 - $20 = $<<60-20=40>>40 kama mabadiliko.
