Answer:
5% or 0.05
Step-by-step explanation:
Diana invested $3000 in savings account 3 years. And the total interest gained by Diana is $450. Therefore,
Principal amount (P) = $3000
Time (t) = 3 years
Total interest (I) = $450
Rate (r) =r
Using the formula,
I = ![\frac{Prt}{100}](https://tex.z-dn.net/?f=%5Cfrac%7BPrt%7D%7B100%7D)
450 =
45000 = 9000×r
r =
=5%
r = 0.05
Hence, the interest rate = 0.05
Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
Cost of per pound= $1.28
If a sack of cornmeal weighs = 4 pounds 12 ounces
First we need to convert ounces into pounds ,
as we know that ,
![1\ pound=16\ ounces\\\\1\ ounce=\frac{1}{16}\ pounds\\\\12\ ounces=\frac{12}{16}\ pounds=0.75\ pounds](https://tex.z-dn.net/?f=1%5C%20pound%3D16%5C%20ounces%5C%5C%5C%5C1%5C%20ounce%3D%5Cfrac%7B1%7D%7B16%7D%5C%20pounds%5C%5C%5C%5C12%5C%20ounces%3D%5Cfrac%7B12%7D%7B16%7D%5C%20pounds%3D0.75%5C%20pounds)
Now, total pounds of cornmeal is given by
![4+0.75=4.75\ pounds](https://tex.z-dn.net/?f=4%2B0.75%3D4.75%5C%20pounds)
Total cost for 4.75 pounds is given by
![4.75\times 1.28=\$6.08](https://tex.z-dn.net/?f=4.75%5Ctimes%201.28%3D%5C%246.08)
So, First Option is correct.
