135
Step-by-step explanation:
<em>1</em>
For this, use the equation I gave you above to find the costs.
<em>2</em>
First, the cost of the printer will <em>NOT</em> change, for the number of printers Eddie needs to buy does not change, he only needs one. This already helps you figure out that 349 is <em>not </em>a coefficient to the variable, n. However, when it comes to the number of blank shirts Eddie needs to buy, the number of he gets <em>does </em>change, this is the dependent variable that makes the cost vary. Using the equation above, you can plug in any number.
For example, 20.
349 + 4.80(20) = 445

For this final part, I just kept using the equation until I got the closest number that is lower than 1000. In this case, 135 got me 997, and 136 was just a few decimals away from 1000, but it was still over.
