Answer:
16
Step-by-step explanation:
3/4 = 0.75
12/0.75=16
<span>i=prt
where i is interest (9000-6000 = $3000 interest)
p is principle ($6000)
r is rate (5.5%) [taking that its 5.5%pa]
t is time
substitute these into the equation
3000 = $6000 x 5.5% x t
t = 3000 divided by (6000x5.5%)
= 3000 divided by 330
t=100/11 years
it would take 100/11 years which is approx 9.1 years</span>

The error was done in Step E, because student did not multiply
by the negative sign in numerator. The real numerator in Step E should be:

Hence, Step E must be
.

The error was done in Step C, because the student omitted the
of the algebraic identity
. Step C must be
