A barbecue grill with an original price of $395 is discounted 65%. What is the sale price?
A$138.25
B$256.75
C$148.25
D$128.75
Answer & Solution
Correct answer: A. $138.25
1. First find the amount of discount: change 65% to a decimal, 0.65.
2. Multiply: 0.65 x 395 = 256.75, so the discount is $256.75.
3. The sale price equals the original price minus the discount.
4. Subtract: 395 - 256.75 = 138.25.
5. So the sale price of the grill is $138.25.
6. $256.75 is the discount itself, the classic trap of stopping one step early.
7. $148.25 and $128.75 come from borrowing errors in the subtraction, which a quick estimate (35% of 400 is about 140) rules out.
