Question

Difficulty: EasyProfit and Loss

Match each buy-and-sell transaction to the correct dollar amount of profit or loss.

  • Buy a tool set for $40\$40 and sell it for $65\$65.$25\$25 Profit
  • Buy a used guitar for $200\$200 and sell it for $150\$150.$50\$50 Loss
  • Buy a blender for $30\$30 and sell it for $30\$30.$0\$0 (Break-even)
  • Buy a winter coat for $85\$85 and sell it for $100\$100.$15\$15 Profit

Answer

Tool set matches $25\$25 Profit; Guitar matches $50\$50 Loss; Blender matches $0\$0 (Break-even); Winter coat matches $15\$15 Profit.
Profit is correctly calculated when the selling price is higher than the cost price. A loss occurs when the selling price is lower than the cost price, and breaking even occurs when the two prices are identical.

Step-by-Step Solution

1
Calculate the difference between the selling price and the cost price for each transaction.
Tool set: $65−$40=$25\$65 - \$40 = \$25. Guitar: $150−$200=−$50\$150 - \$200 = -\$50. Blender: $30−$30=$0\$30 - \$30 = \$0. Coat: $100−$85=$15\$100 - \$85 = \$15.
The difference determines the amount of money gained or lost on each item.
2
Determine if each result is a profit, loss, or break-even.
Positive values ($25\$25, $15\$15) are profits. The negative value (−$50-\$50) is a loss. Zero ($0\$0) is a break-even.
A positive difference means money was made (profit), a negative difference means money was lost (loss), and zero means no change in value.
