Question: Maya bought the following items at the grocery store:
• 3 cartons of milk — $3.49 per carton
• 1 block of cheese — $6.25
• 5 bags of pretzels — $4.20 per bag
• 2 boxes of cereal — $5.80 per box
• 4 containers of yogurt — $1.25 per container
How much will Maya spend in dollars and cents on milk and pretzels?
1. **State the problem:** We need to find the total cost Maya will spend on milk and pretzels only.
2. **Identify the quantities and prices:**
- Milk: 3 cartons at $3.49 each
- Pretzels: 5 bags at $4.20 each
3. **Write the formula for total cost:**
$$\text{Total Cost} = (\text{Quantity of Milk} \times \text{Price per Milk}) + (\text{Quantity of Pretzels} \times \text{Price per Pretzels})$$
4. **Substitute the values:**
$$\text{Total Cost} = (3 \times 3.49) + (5 \times 4.20)$$
5. **Calculate each part:**
$$3 \times 3.49 = 10.47$$
$$5 \times 4.20 = 21.00$$
6. **Add the two amounts:**
$$10.47 + 21.00 = 31.47$$
7. **Final answer:** Maya will spend **$31.47** on milk and pretzels.
