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.

Question

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

Answer 1

To determine the total cost for an order of $x$ ink cartridges, we need to take into account the cost of the cartridges and the flat shipping fee.

The cost of the ink cartridges is given by: $$19x$$ where $19$ is the cost of each cartridge and $x$ is the number of cartridges purchased.

The flat shipping fee is $7.50$.

Therefore, the algebraic expression for the total cost $C$ for an order of $x$ cartridges can be written as: $$C=19x+7.50$$
