Let's go step by step through the events and keep track of the debt: ### **Step 1** - **Someone has a debt of $100.** - **Debt:** **-$100** ### **Step 2** - **That person reduces the debt to $50.** - The person pays off $50. - **Debt:** **-$50** ### **Step 3** - **The person is then offered credit of $1000 to buy things.** - This means the person can now borrow up to $1000. - **Available credit:** $1000 (not debt yet) - **Debt:** **-$50** (unchanged) ### **Step 4** - **The person buys $1100 worth of goods.** - The person uses all $1000 of their credit, and still needs $100 more. Since they only had $1000 in credit, the extra $100 might be added to their debt. - Total amount spent = $1100. - **Debt increases by $1100.** - **Debt:** -$50 (old debt) + $1100 (new purchases) = **-$1150** ### **Step 5** - **The person ends up with $750 worth of debt.** - There must have been a payment or return/refund. - Difference: -$1150 (previous debt) to -$750 (current debt) = **$400** was reduced (maybe by paying $400 back or returning $400 worth of goods). - **Debt:** **-$750** ### **Step 6** - **The person gets a store credit of $39.** - This reduces their debt by $39 (as a refund or store credit). - **Debt:** -$750 + $39 = **-$711** ### **Step 7** - **The person buys some more things using their credit cards.** - The amount is **not specified**, so let's call it **$X**. - **Final Debt:** **-$711 - X** --- ## **Summary Table** | Step | Description | Debt Calculation | Debt | |------|----------------------------------------------|---------------------|-----------| | 1 | Initial debt | | -$100 | | 2 | Pays off $50 | -100 + 50 | -$50 | | 3 | Gets $1000 credit | (No change yet) | -$50 | | 4 | Buys $1100 worth of goods | -50 - 1100 | -$1150 | | 5 | After reducing $400 of debt | -1150 + 400 | -$750 | | 6 | Gets $39 store credit | -750 + 39 | -$711 | | 7 | Buys more with credit card ($X) | -711 - X | -$711 - X | ### **Final Answer** After all the described transactions, the person's debt is **-$711** **plus whatever additional amount (X) they spend with their credit card in the last step**. **Final debt = $711 + (amount spent in last step)** If you want to use a specific value for the last purchase, just subtract it from -$711.
