An investment that yielded 6% simple interest came due at the end of the
year. Dominic received a check for
the total amount (interest plus principal)
of $169.60.
What was his original investment?

principal = $160

Step-by-step explanation:

A = p(1+rt)

169.60 = p(1+0.06 x 1)

169.60 = 1.06p

p = 169.60 / 1.06 = 160

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
