Let's break down the costs for ink cartridges based on the given information.
- Cost of Ink Cartridges: Each ink cartridge costs $19.
- Flat Rate Shipping: The shipping cost is a flat rate of $7.50, regardless of the number of cartridges purchased.
Total Cost Calculation
If you want to buy n ink cartridges, the total cost can be calculated with the following formula:
\[ \text{Total Cost} = (19 \times n) + 7.50 \]
Where:
- \( n \) = number of cartridges purchased.
- \( 19 \times n \) = total cost of the cartridges.
- \( 7.50 \) = flat shipping cost.
Example Calculations
-
If you buy 1 cartridge: \[ \text{Total Cost} = (19 \times 1) + 7.50 = 19 + 7.50 = 26.50 \]
-
If you buy 2 cartridges: \[ \text{Total Cost} = (19 \times 2) + 7.50 = 38 + 7.50 = 45.50 \]
-
If you buy 5 cartridges: \[ \text{Total Cost} = (19 \times 5) + 7.50 = 95 + 7.50 = 102.50 \]
