katrin2010 [14]

Answer:

Initial amount P = $12000

Interest after 2 years I = 4%*2 = 8%

Investment into Trust fund:

$12000 + $5000 + 0.08*$12000 = $17960

Interest amount to exceed $20000:

$20000 - $17960 = $2040

Time required to get $2040:

17960*0.045x = 2040
808.2x = 2040
x = 2040/808.2
x = 2.52 years

The investment will exceed $20000 in the second half of the third year

Solve tor r. *a(5 – x) = bz - 8

Mars2501 [29]

Answer:

See explanation

Step-by-step explanation:

Assuming the given equation is

$a(5 - r) = bz - 8$

To solve for r, we first divide both sides by a.

$5 - r = \frac{ bz - 8}{a}$

We now subtract 5 from both sides:

$- r = \frac{ bz - 8}{a} - 5$

We now divide through by - 1 to get:

$r = 5 - \frac{ bz - 8}{a}$

$r = \frac{5a - bz + 8}{a} \: \: where \: a \ne0$
