Answer: $336
explanation: 60% is equal to .6 so just take $210 and multiply that by .6 to get $126. Now, just take $126 and add it to $210 and you have $336.

Answer:
<em>The decay rate 'm' is 0.25</em>
Step-by-step explanation:
As given,
Average Life time of New cell phone = 4 years
Lifetime of phone = L = ?
<em>L</em><em> is a random variable defining lifetime of a cell phone.</em>
L∼
Exponential (m)
Mean of Exponential Distribution = ![\frac{1}{m}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bm%7D)
As, they follow exponential distribution, so to find decay rate , we simply can write it as :
= 4
or
![m = \frac{1}{4}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
<em><u>m=0.25</u></em>
L∼
Exponential (0.25)
<em>The decay rate is 0.25</em>
