Given:
Principal = $10
Rate of simple interest = 2.2% per month
Number of years = 6
To find:
The value of interest.
Solution:
Formula for simple interest is:
...(i)
Where, P is principal, r is rate of interest in % and t is the time period.
Here the rate of interest is defined for per month. So, the time period is also the number of months.
[ 1 year = 12 months ]
Putting P=10, r=2.2 and t=72 in (i), we get
The simple interest is $15.84.
Therefore, the correct option is B.
Answer:
Answer
Step-by-step explanation:
The answer is C
You would do 1.2 ÷ 4 which is 0.3
2.4 ÷ 8 is 0.3
3.9 ÷ 18 is 0.3
A is wrong because the constant of proportionality is 0.33333
B is wrong because the constant of proportionality is 0.6
No Problem!
1. Add y to each side
That will get you 3x=8+y
2. Subtract 8 on each side
That will get you y=3x-8
Answer:
you have to do the math for each one to get the answer i dont know sorry bro
Step-by-step explanation:
X / 5 = 80
x = 80 * 5
x = 400.......so the total of the numbers added was 400
(400 - x) / 4 = 50
400 - x = 50 * 4
400 - x = 200
-x = 200 - 400
-x = -200
x = 200 <== the removed number
