<human>:  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?
<bot>: How much does 2 liters of mustard oil cost? ** The cost of 2 liters of mustard oil is $13 x 2 = $<<13*2=26>>26.
How much does 3 pounds of gluten-free penne pasta cost? ** The cost of 3 pounds of gluten-free penne pasta is $4 x 3 = $<<3*4=12>>12.
How much did Jerry spend? ** So, Jerry spent a total of $26 + $12 + $5 = $<<26+12+5=43>>43 for grocery shopping.
How much money will Jerry have? ** Thus, Jerry will have $50 - $43 = $<<50-43=7>>7 for himself.
