1. Max spent $3.40.
- Bananas: 30% off $3.00 = $0.90 discount → $2.10
- Apples: 40% off $2.00 = $0.80 discount → $1.20
- Total: $2.10 + $1.20 = $3.40
2. John spent $12.80.
- Total before discount: $5.00 + $4.00 + $7.00 = $16.00
- 20% off: 0.20 × $16.00 = $3.20 discount
- Total after discount: $16.00 - $3.20 = $12.80
3. Michelle spent $15.00.
- Hot dog: $3.25
- Hamburger: $4.20
- Sub: $5.50
- Sodas: 3 × $1.25 = $3.75; 50% off → $1.875 (rounded to $1.88)
- Total: $3.25 + $4.20 + $5.50 + $1.88 = $14.83 (Note: The problem likely expects exact calculation without rounding, so $3.25 + $4.20 + $5.50 + $1.875 = $14.825, which rounds to $14.83. However, if we assume the soda price is meant to be exactly half of $3.75, then it's $1.875, and total is $14.825. But since money is usually to two decimals, the answer should be $14.83. If the problem expects no rounding, then perhaps it's $15.00 as stated, but that doesn't add up. Let me recalculate: $3.25 + $4.20 + $5.50 = $12.95; sodas: 3 × $1.25 = $3.75, half is $1.875, so total $12.95 + $1.875 = $14.825, which is $14.83 when rounded. But the provided answer says $15.00, which is incorrect. I will correct this: Michelle spent $14.83.)
Correction: Michelle spent $14.83.
- Hot dog: $3.25
- Hamburger: $4.20
- Sub: $5.50
- Sodas: 3 × $1.25 = $3.75; 50% off → $1.875 (which is $1.88 when rounded to nearest cent)
- Total: $3.25 + $4.20 + $5.50 + $1.88 = $14.83
4. Shannon spent $10.50 and got $9.50 in change.
- Book: $7.99
- Magazine: $4.25
- Bookmark: $1.99
- Total before discount: $7.99 + $4.25 + $1.99 = $14.23
- 15% off: 0.15 × $14.23 = $2.1345 (rounded to $2.13)
- Total after discount: $14.23 - $2.13 = $12.10
- She paid with $20.00, so change: $20.00 - $12.10 = $7.90
Correction: Shannon spent $12.10 and got $7.90 in change.
Let me recheck the math for problem 4:
- Book: $7.99
- Magazine: $4.25
- Bookmark: $1.99
- Sum: $7.99 + $4.25 = $12.24; $12.24 + $1.99 = $14.23
- 15% of $14.23: 0.15 × 14.23 = 2.1345, which rounds to $2.13
- Discounted total: $14.23 - $2.13 = $12.10
- Change from $20: $20.00 - $12.10 = $7.90
So the correct answer for problem 4 is: Shannon spent $12.10 and got $7.90 in change.
However, the original answer provided in the image might have a different calculation. Since I must solve based on standard math, I'll provide the accurate solution.
Final corrected answers:
1. Max spent $3.40.
2. John spent $12.80.
3. Michelle spent $14.83.
4. Shannon spent $12.10 and got $7.90 in change.
