discount word problems. Since I can't view images directly, I’ll solve the problems based on the text you’ve provided in your message. Here are the problems and their solutions:

Problem 1:
> What percent discount is $120? A store has a sale where they decide to sell a calculator at $64. Find the selling price of the calculator.
Wait — this seems misworded. It says "What percent discount is $120?" — that doesn’t make sense because $120 is a dollar amount, not a percentage. Let’s re-express it logically.
Let’s assume the
original price is $120, and the
sale price is $64. We are to find the
percent discount.
#### Step-by-step:
- Original price = $120
- Sale price = $64
- Amount saved = $120 - $64 = $56
- Percent discount = (Amount saved / Original price) × 100
= ($56 / $120) × 100
= 0.4667 × 100
≈
46.67%
✔ Answer: The discount is approximately
46.67%.

Problem 2:
> The marked price of a shop is listed as $398. It has a discount of 10%. What is the selling price?
- Marked price = $398
- Discount = 10% of $398 = 0.10 × 398 = $39.80
- Selling price = $398 - $39.80 =
$358.20
✔ Answer: The selling price is
$358.20.

Problem 3:
> A leather jacket marked at $110 is sold at 10% off. What is the sale price of the jacket?
- Marked price = $110
- Discount = 10% of $110 = 0.10 × 110 = $11
- Sale price = $110 - $11 =
$99
✔ Answer: The sale price is
$99.

Problem 4:
> After a shopping spree, Sandra has $150 left after spending $450 of the bill. What was the original amount?
Wait — this wording is ambiguous. Let's interpret carefully.
She spent $450 and has $150 left. So the total amount she started with is:
- Original amount = Amount spent + Amount left
= $450 + $150 =
$600
✔ Answer: The original amount was
$600.

Problem 5:
> The price of a watch is $25. If you buy 3 watches, you will get a 15% discount on the total bill. How much would you pay if you buy 3 watches?
- Price per watch = $25
- Total for 3 watches = 3 × $25 = $75
- Discount = 15% of $75 = 0.15 × 75 = $11.25
- Final amount to pay = $75 - $11.25 =
$63.75
✔ Answer: You would pay
$63.75.
