Printer ink cartridges cost $19 each. The company that sells the ink cartridges charges a flat rate of $7.50, no matter how many ink cartridges you buy.

Write an algebraic expression that describes the total cost for a single order of `x`, cartridges.

To determine the total cost \( C \) for an order of \( x \) ink cartridges, you can consider both the cost of the ink cartridges and the flat shipping fee.

  1. The cost for \( x \) ink cartridges, each priced at $19, is represented as: \[ 19x \]

  2. The flat shipping fee is $7.50, which remains constant regardless of the number of cartridges purchased.

Now, combining both costs, the total cost \( C \) can be expressed algebraically as: \[ C = 19x + 7.50 \]

This expression represents the total cost for ordering \( x \) ink cartridges including the shipping fee.
