Given:
Principal value = $1200
Rate of interest = 3% per year
To find:
The interest earned by Jenny in one year.
Solution:
Formula of interest:
Where, P is principal, r is rate of interest and t is time.
We have, P = 1200, r = 3, t=1. Putting these values, we get
The interest earned by Jenny in one year is $36.
Therefore, the correct option is A.
Answer:
"No Solution"
Step-by-step explanation:
We can use the log property shown below to simplify this:
Since no "base" is given, we take base as "10" and use property to write:
Now, we solve for x:
But we are NOT done. We have to take the value and put it into the equation to check if there is any NEGATIVE value, because we cannot take negative log.
Putting in LHS:
Log(2x - 7)
Log(2(-3) - 7)
Log(-6-7)
Log(-13)
This can't be solved. So x = -3 is not a solution. Thus, there is NO SOLUTION to the equation given.
