Looking at the worksheet, I need to solve problem #1:
"A painting is on sale at 50% off. The sale price is $320. What was the original price?"
Let me think through this step by step.
If something is 50% off, that means you're paying half of the original price. So the sale price ($320) represents 50% of what it originally cost.
To find the original price, I need to figure out what number has 50% equal to $320.
Since 50% = 1/2, then:
Original Price × 1/2 = $320
To find the original price, I multiply both sides by 2:
Original Price = $320 × 2 = $640
Let me check my answer:
- Original price: $640
- 50% off means you save: $640 × 0.50 = $320
- Sale price: $640 - $320 = $320 ✓
That matches the given sale price, so my answer is correct.
Final Answer: $640
