Which expressions are equivalent to the one below? Check all that apply.
dem82 [27]

Answer:

Recall from Logarithm law Log a - Log b = Log (a/b)

so, Log 2 - Log 4 = Log ( 2/4)

                            = Log ( 1/2).

Also from the law

Log (a/b) = Log a - Log b

i.e Log (1/2) = Log 1 - Log 2

Recall: Log 1 = 0

which implies : Log 1 - Log 2 = 0 - Log 2

                                               = - Log 2

Mrac [35]
You can use the simple interest formula 
P = irt

We need P, which is the primary (or principal) investment, and we know that:

rate = 3% (0.03)
time = 7
i = $25000

So, just plug in and solve:
I = 25000(0.03)(7)
I = 5250

The company needs to invest $5250 today, to make $25000 in 7 years.
