Answer:
It will take 146 days to earn an interest of $80.
Step-by-step explanation:
The simple interest formula is:
![I=\frac{P\times r\times t}{100}](https://tex.z-dn.net/?f=I%3D%5Cfrac%7BP%5Ctimes%20r%5Ctimes%20t%7D%7B100%7D)
It is provided that:
I = $80
P = $4,000
r = 5% p.a.
Compute the time required as follows:
![I=\frac{P\times r\times t}{100}](https://tex.z-dn.net/?f=I%3D%5Cfrac%7BP%5Ctimes%20r%5Ctimes%20t%7D%7B100%7D)
![t=\frac{I\times 100}{P\times r}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7BI%5Ctimes%20100%7D%7BP%5Ctimes%20r%7D)
![=\frac{80\times 100}{4000\times 5}\\\\=0.4\ \years\\\\=0.4\times 365\ days\\\\=146\ days](https://tex.z-dn.net/?f=%3D%5Cfrac%7B80%5Ctimes%20100%7D%7B4000%5Ctimes%205%7D%5C%5C%5C%5C%3D0.4%5C%20%5Cyears%5C%5C%5C%5C%3D0.4%5Ctimes%20365%5C%20days%5C%5C%5C%5C%3D146%5C%20days)
Thus, it will take 146 days to earn an interest of $80.
If you would like to know how many muffins did Elsa bake, you can calculate this using the following steps:
2/5 of all of the muffins = 4 muffins
2/5 * x muffins = 4
2/5 * x = 4 /*(5/2)
x = 4 * 5/2
x = 10 muffins
The correct result would be 10 muffins.

Answer:
the correct answer should be A
Answer:
y = x + 6
Step-by-step explanation:
y = x + b
when x = 0, y = 6. so....
6 = (0) + b
6 = b
so, y = x + 6
