58% is the answer. 7 dividing 12= 0.5833333
you much move the decimal over two places and you would get 58%
We need to use the formula for simple interest which is
I= prt
Where I is the amount of money you earned or pay in interest
p is the principal, the amount you deposited or borrowed
r is the interest rate expressed as a decimal
t is time in terms of years
In this problem, I= 1,680
p= 3000
t= 8
'. r is what we are looking for.
Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...
The first incorrect is the second step so choice B. ,bc. the exponents need assuming not multiply

4×6=24, 24+24=48
or
(4×6)+(4×6)=2×4×6=8×6
