Answer:
Option C
Step-by-step explanation:
Given expression in the question is,
y = 
To get the value of t,
Take the log on both the sides of the expression,
log(
) = ![\text{log}[(2^{\frac{t}{30}})]](https://tex.z-dn.net/?f=%5Ctext%7Blog%7D%5B%282%5E%7B%5Cfrac%7Bt%7D%7B30%7D%7D%29%5D)
log() = 
t = 
t = ![30[\text{log}_2(\frac{y}{7})]](https://tex.z-dn.net/?f=30%5B%5Ctext%7Blog%7D_2%28%5Cfrac%7By%7D%7B7%7D%29%5D)
[Since, 
]
Therefore, Option C will be the answer.
Answer:

6x6x3.14
=113
4×2=8. 100×2=200
8% out of 200
so
4=8 if you have double, 200
Answer:
$44.94
Step-by-step explanation:
400+100+100 = 600
22.40 + 10 +10 = 42.40
(22.40 for the first 400 and 10 for each additional 100)
If tax is 6%, you can multiply the whole thing (42.40) by 1.06 to get the total amount of 44.94.
Why 1.06? If you think about it, tax is 6%. 6% is the same as 0.06. You pay 100% for the products, so with tax, it's the equivalent of 106%, or 1.06.
