Seven units long. The distance between 2 sides, in this example is 6, and -1. The distance between 6 and -1 is 7, so when you add units, you get 7 units.

You would start by finding out how much 10 and 20 cost per copy
10: 40-25 = 15/10 = $1.50 dollars per copy
20 (This is for checking your math, not required): 55-25 = 30/20 = $1.50 dollars per copy
So, to find 15 copies you would use this formula: 25 + 1.5x
25 + 1.5(15)
25 + 22.5
$47.50 for 15 copies
Now for the second question:
160 - 25 = 135/1.5 = 90 copies
90 copies for $160
Answer:
Step-by-step explanation:
u can also express the quotient remainder as a fraction or decimal. You can calculate the decimal by first placing a decimal point following your quotient of 2 and then continuing long division by adding a zero to your remainder, transforming it from 4 to 40. The number 8 goes into 40 five times, resulting in a final quotient of 2.5. So, if, for example, this was a monetary transaction in which you had to divide $20 between eight people, this quotient with the decimal remainder determines that each person receives $2.50. To convert this decimal to a fraction, you would translate .5 to 5/10, then reduce it to its lowest terms, which would be 1/2.
