To calculate the total purchase from the grocery store, we can break down the steps as follows:
Step 1: Calculate the Cost of Each Item
-
Cheese:
- Price: $2.99/lb
- Weight: 0.5 lb
- Cost: \( 0.5 \times 2.99 = 1.495 \) (approximately $1.50)
-
Sliced Ham:
- Price: $4.29/lb
- Weight: 2 lbs
- Cost: \( 2 \times 4.29 = 8.58 \)
-
Bread:
- Price: $2.49/loaf
- Quantity: 2 loaves
- Cost: \( 2 \times 2.49 = 4.98 \)
-
Potato Chips:
- Price: $1.99 each (or 2 for $3.00)
- Quantity: 3 bags
- Cost Calculation:
- For 2 bags: $3.00
- For 1 more bag: $1.99
- Total cost for chips: \( 3.00 + 1.99 = 4.99 \)
-
Salsa:
- Price: $3.39/container
- Quantity: 2 containers
- Cost: \( 2 \times 3.39 = 6.78 \)
Step 2: Calculate Subtotal Before Discounts
Now, we can add up the costs of all items to find the subtotal:
- Cheese: $1.50
- Sliced Ham: $8.58
- Bread: $4.98
- Potato Chips: $4.99
- Salsa: $6.78
Subtotal:
\[ 1.50 + 8.58 + 4.98 + 4.99 + 6.78 = 26.83 \]
Step 3: Apply Discounts
Now, we need to determine if we can use any discounts:
-
Coupon for $3.00 off if the total is more than $25.00:
- Our subtotal is $26.83, which qualifies for this coupon.
-
10% off if total is more than $30.00:
- Our subtotal does not qualify for this discount.
Since the subtotal qualifies for the $3.00 off coupon, we will use that.
New total after coupon:
\[ 26.83 - 3.00 = 23.83 \]
Step 4: Calculate Sales Tax
Now, calculate the sales tax:
- Sales Tax: 4% of $23.83
\[ \text{Sales Tax} = 0.04 \times 23.83 = 0.9532 \] (approximately $0.95)
Step 5: Calculate Final Total Cost
Finally, add the sales tax to the total after the coupon:
Final Total:
\[ 23.83 + 0.95 = 24.78 \]
Summary of Calculations
- Total cost before discounts: $26.83
- Discount applied: $3.00
- Total after discount: $23.83
- Sales tax (4%): $0.95
- Final Total Cost: $24.78
Conclusion
The total cost of your purchases, after applying the appropriate discount and including tax, is $24.78.
