1. Percent error is
![| \frac{guess-actual}{actual}|](https://tex.z-dn.net/?f=%7C%20%5Cfrac%7Bguess-actual%7D%7Bactual%7D%7C%20)
The guess is 15.5mi, and the actual distance is 14.5 mi.
Percent error is
![| \frac{15.5-14.5}{14.5}|=0.69=6.9%](https://tex.z-dn.net/?f=%7C%20%5Cfrac%7B15.5-14.5%7D%7B14.5%7D%7C%3D0.69%3D6.9%25)
2. The cost will be $31.95*(1+0.075) = $34.35
The 1 represents 100% of the original amount of $31.95, and now we add 7.5% (0.075) to the 100%. In other words we multiply $31.95 by 107.5%.
3. His commission will be $165 out of $4125, or $165/$4215 = 0.039 = 3.9%
4. The principal (amount of money you start with) is $12000, and the interest rate is 15% of that.
15% of $1800 = 0.15*$12000 = $1800
Answer:
Step-by-step explanation:
5y + x = 25
Subtract x from both sides when x = 5
5y + x - x = 25 - x
5y = 20
5y/5 = 20/5
=4
Y=4
