A printer charges a fixed setup cost plus $15 for every 100 cpoies if 300 copies cost $75 ,how much will 1000 copies cost

the fixed setup cost must be 75-45=30

so, 1000 copies cost

30 + 10*15

To determine the cost of 1000 copies, we first need to find the cost of 300 copies. We know that 300 copies cost $75, so we can set up the following equation:

300 copies cost = $75

Next, we need to calculate the cost per copy for 300 copies. We divide the cost by the number of copies:

Cost per copy = $75 / 300 copies = $0.25 per copy

Now, we can use the cost per copy to find the cost of 1000 copies. We know that the printer charges $15 for every 100 copies. Since 1000 copies is ten times the amount of 100 copies, we can multiply the cost per copy by 10:

Cost per copy = $0.25 per copy
Cost for 1000 copies = $0.25 x 10 = $2.50 per copy

Finally, we need to add the fixed setup cost to the cost of 1000 copies. As the setup cost is not provided in the question, we cannot determine the final cost without this information.
