conversations.value: Can you give me some step-by-step instructions for this math problem: The cash price of a refrigerator was $8000. Samantha wanted to buy the refrigerator but pay in installments. If she paid a deposit of $3000 and paid 30 equal monthly installments of $300 each, calculate how much money she would have saved by paying cash.
conversations.from: assistant
conversations.value: When Samantha paid $300 in 30 equal monthly installments, she paid a total of $9000
  Since the higher purchase is a deposit plus the total monthly installments, Samatha paid $3000+$9000=$12000 for the refrigerator on higher purchase.
  If she would have bought the refrigerator on the cash prize, Samantha would have paid $12000- to $8000= $4000 less.
