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

### Instruction:
Mark goes into the store to buy some groceries.  He buys 6 2$ cans of soup, 2 $5 loaves of bread, 2 3$ boxes of cereal, and 2 $4 gallons of milk.  When he gets to the register, he opens his wallet to pay and realizes he only has $10 bills in there.  How many $10 bills does he need to use to pay?

### Response:
 Mark ananunua makopo 6 ya supu yenye thamani ya $2 kila moja, maana yake anatumia 6*$2=$<<6*2=12>>12 kwenye supu.
Mark ananunua mikate 2 ya mkate yenye thamani ya $5 kila moja, maana yake anatumia 2*$5=$<<2*5=10>>10 kwenye mkate.
Mark ananunua masanduku 2 ya nafaka yenye thamani ya $3 kila moja, maana yake anatumia 2*$3 = $<<2*3=6>>6 kwenye nafaka.
Mark ananunua galoni 2 za maziwa zenye thamani ya $4 kila moja, maana yake anatumia 2*$4 = $<<2*4=8>>8 kwenye maziwa.
Vitu vyote vikiwa vimeongezwa pamoja, hii inamaanisha Mark anatumia $12+$10+$6+$8 = $<<12+10+6+8=36>>36
Kwa kuwa Mark ana noti za $10 tu, anatumia $36/$10 = 3 na nusu ya noti za $10, ambayo inakaribia 4 kwa kuwa huwezi kutumia nusu ya kitu kisichogawika.
