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.

HINT: Use the table to help you write the expression.

Total Cost

19\left(1\right)\ +\ 7.50

Answer 1

To find the total cost for purchasing \( x \) ink cartridges, you can use the given information:

1. Each ink cartridge costs $19.
2. There is a flat shipping charge of $7.50.

To express the total cost \( C \) as an algebraic expression for \( x \) cartridges, you can sum the cost of the cartridges and the flat shipping charge.

The cost of \( x \) cartridges is given by \( 19x \).

Therefore, the total cost \( C \) can be written as:

\[ C = 19x + 7.50 \]

This expression represents the total cost for an order of \( x \) ink cartridges.

Answer 2

thank you and how do i fill out the rest of the chart

Answer 3

To fill out the rest of the chart, we can use the algebraic expression we derived:

\[ C = 19x + 7.50 \]

This means we'll plug in different values for \( x \) (the number of cartridges) and calculate the total cost \( C \).

Here's how you can fill out the chart:

1. For \( x = 1 \): \[ C = 19(1) + 7.50 = 19 + 7.50 = 26.50 \]

2. For \( x = 2 \): \[ C = 19(2) + 7.50 = 38 + 7.50 = 45.50 \]

3. For \( x = 3 \): \[ C = 19(3) + 7.50 = 57 + 7.50 = 64.50 \]

4. For \( x = 4 \): \[ C = 19(4) + 7.50 = 76 + 7.50 = 83.50 \]

Now, you can fill out the table based on these calculations:

| Number of Cartridges \( x \) | Total Cost \( C \) | |-------------------------------|---------------------| | 1 | $26.50 | | 2 | $45.50 | | 3 | $64.50 | | 4 | $83.50 |

This chart now reflects the total cost for 1, 2, 3, and 4 ink cartridges, including the flat shipping fee.
