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

### Instruction:
Jerry was asked by her mom to do grocery shopping. He needs to buy 2 liters of mustard oil that costs $13 per liter, 3 pounds of gluten-free penne pasta that costs $4 per pound, and 1  pound of pasta sauce that costs $5. If Jerry can keep the rest of the $50 after grocery shopping, how much money will he have?

### Response:
 Mafuta ya mharage yatagharimu 2 x $13 = $<<2*13=26>>26.
Pasta ya penne isiyo na gluteni itagharimu 3 x $4 = $<<3*4=12>>12.
Jumla ya gharama ya ununuzi wa vyakula ni $26 + $12 + $5 = $<<26+12+5=43>>43.
Jerry atakuwa na $50 - $43 = $<<50-43=7>>7 kwa ajili yake mwenyewe.
