Answer: $389.35
Step-by-step explanation: Multiply $599 by .65, to get the 35% off price.
There is also another way you can do this kind of problem. You multiply $599 by .35, then subtract that number from 599. I prefer the first method because it is faster.
Answer:
The ultra-marathon Idita Rod Trail is about 38 times longer than the Boston Marathon.
Step-by-step explanation:
Let
x -----> the length of the Boston Marathon in meters
y -----> the length of the Idita rod Trail Invitational ultra-marathon in meters
we have
![x=4.2*10^4\ m](https://tex.z-dn.net/?f=x%3D4.2%2A10%5E4%5C%20m)
![y=1.6*10^6\ m](https://tex.z-dn.net/?f=y%3D1.6%2A10%5E6%5C%20m)
we know that
To find out how many times as long is the course of the Idita rod Trail ultra-marathon as that of the Boston Marathon, divide the length of the Idita rod Trail Invitational ultra-marathon by the length of the Boston Marathon
so
![\frac{y}{x}](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7Bx%7D)
![\frac{x}{y}=\frac{1.6*10^6}{4.2*10^4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%3D%5Cfrac%7B1.6%2A10%5E6%7D%7B4.2%2A10%5E4%7D)
Remember that
To divide two numbers in scientific notation, divide their coefficients and subtract their exponents
![\frac{1.6*10^6}{4.2*10^4}=\frac{1.6}{4.2}*(10^{6-4})=0.381*(10^{2})=38.1](https://tex.z-dn.net/?f=%5Cfrac%7B1.6%2A10%5E6%7D%7B4.2%2A10%5E4%7D%3D%5Cfrac%7B1.6%7D%7B4.2%7D%2A%2810%5E%7B6-4%7D%29%3D0.381%2A%2810%5E%7B2%7D%29%3D38.1)
therefore
The ultra-marathon Idita Rod Trail is about 38 times longer than the Boston Marathon.
