Answer:
x=11
Step-by-step explanation:
Well, first let’s add up how much Steve spent in total. So, 3+12+6 which equals 21. Steve had $25 left so add the leftover to the amount spent which would be 25+21=46
The answer to your problem is 360
Answer:
The correct solution is "4.6".
Step-by-step explanation:
Given:
Interest rate,
r = 6.2%
or,
= 0.062
Amount,
A = 100000
Principle,
P = 76000
As we know,
⇒ ![A=P(1+\frac{r}{100} )^n](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7B100%7D%20%29%5En)
On substituting the values, we get
⇒ ![100000=76000(1+\frac{6.2}{100} )^n](https://tex.z-dn.net/?f=100000%3D76000%281%2B%5Cfrac%7B6.2%7D%7B100%7D%20%29%5En)
⇒ ![(1+0.062)^n=\frac{100}{76}](https://tex.z-dn.net/?f=%281%2B0.062%29%5En%3D%5Cfrac%7B100%7D%7B76%7D)
On taking log both sides, we get
⇒ ![n \ log_e(1.062)=log_e(\frac{100}{76} )](https://tex.z-dn.net/?f=n%20%5C%20log_e%281.062%29%3Dlog_e%28%5Cfrac%7B100%7D%7B76%7D%20%29)
⇒ ![n=\frac{ln(\frac{100}{76} )}{ln(1.062)}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7Bln%28%5Cfrac%7B100%7D%7B76%7D%20%29%7D%7Bln%281.062%29%7D)
By putting the values of log, we get
⇒ ![=4.5622](https://tex.z-dn.net/?f=%3D4.5622)
or,
⇒
