Problem Analysis and Solution

The image contains four word problems involving percentages. Let's solve each problem step by step.

---

Problem 1:

Max went to the local farmer’s market to buy some fresh produce. He bought bananas for 30% off $3.00. He also bought a half dozen apples for 40% off $2.00. How much did he spend?

#### Step-by-Step Solution:
1. Bananas:
- Original price of bananas = $3.00
- Discount = 30% off
- Discount amount = \( 30\% \times 3.00 = 0.30 \times 3.00 = 0.90 \)
- Final price of bananas = \( 3.00 - 0.90 = 2.10 \)

2. Apples:
- Original price of apples = $2.00
- Discount = 40% off
- Discount amount = \( 40\% \times 2.00 = 0.40 \times 2.00 = 0.80 \)
- Final price of apples = \( 2.00 - 0.80 = 1.20 \)

3. Total Amount Spent:
- Total = Price of bananas + Price of apples
- Total = \( 2.10 + 1.20 = 3.30 \)

#### Final Answer for Problem 1:
\[
\boxed{3.30}
\]

Problem 2:

John went shopping for his mom’s birthday. He purchased a pair of gloves for $5.00, a scarf for $4.00, and a knit hat for $7.00. When he got to the register, he used a 20% off coupon. How much did he spend?

#### Step-by-Step Solution:
1. Calculate the total original price:
- Gloves = $5.00
- Scarf = $4.00
- Knit hat = $7.00
- Total original price = \( 5.00 + 4.00 + 7.00 = 16.00 \)

2. Apply the 20% discount:
- Discount amount = \( 20\% \times 16.00 = 0.20 \times 16.00 = 3.20 \)
- Final price after discount = \( 16.00 - 3.20 = 12.80 \)

#### Final Answer for Problem 2:
\[
\boxed{12.80}
\]

Problem 3:

Michelle went to the corner deli. She bought her sister a hot dog for $3.25, her a hamburger for $4.20, and a vegetable stir fry sub for herself for $5.50. She also bought 3 large sodas for $1.25 each but the sodas were 50% off. How much did she spend?

#### Step-by-Step Solution:
1. Calculate the cost of the hot dog, hamburger, and sub:
- Hot dog = $3.25
- Hamburger = $4.20
- Sub = $5.50
- Total for these items = \( 3.25 + 4.20 + 5.50 = 12.95 \)

2. Calculate the cost of the sodas:
- Price per soda = $1.25
- Number of sodas = 3
- Total original price for sodas = \( 1.25 \times 3 = 3.75 \)
- Discount on sodas = 50% off
- Discount amount = \( 50\% \times 3.75 = 0.50 \times 3.75 = 1.875 \)
- Final price for sodas = \( 3.75 - 1.875 = 1.875 \)

3. Calculate the total amount spent:
- Total = Cost of hot dog, hamburger, and sub + Cost of sodas
- Total = \( 12.95 + 1.875 = 14.825 \)

#### Final Answer for Problem 3:
\[
\boxed{14.83}
\]

Problem 4:

Shannon went to the book store. She bought a book for $7.99, a magazine for $4.25, and a bookmark for $1.99. Her purchase was 15% off. She handed the cashier a $20 bill. How much did she spend and how much change did she get back?

#### Step-by-Step Solution:
1. Calculate the total original price:
- Book = $7.99
- Magazine = $4.25
- Bookmark = $1.99
- Total original price = \( 7.99 + 4.25 + 1.99 = 14.23 \)

2. Apply the 15% discount:
- Discount amount = \( 15\% \times 14.23 = 0.15 \times 14.23 = 2.1345 \)
- Final price after discount = \( 14.23 - 2.1345 = 12.0955 \approx 12.10 \) (rounded to two decimal places)

3. Calculate the change:
- Amount paid = $20.00
- Change = \( 20.00 - 12.10 = 7.90 \)

#### Final Answers for Problem 4:
- Amount spent: \(\boxed{12.10}\)
- Change received: \(\boxed{7.90}\)
