Answer:
9.99 years
Step-by-step explanation:
P=$3,500
r=7%=0.07
n=4(quarterly)
A= double of $3,500=
$3,500×2=$7,000
t=?
A=p(1+r/n)^nt
$7,000=$3,500(1+0.07/4)^4t
$7,000=$3,500(1+0.0175)^4t
$7,000=$3,500(1.0175)^4t
Divide both sides by $3,500
2=(1.0175)^4t
Take the log to base 10 of both sides
log2=4t × log1.0175
0.30103=4t × 0.00753
0.30103=4(0.00753)t
0.30103=0.03012t
t=0.30103/0.03012
t=9.99435
Approximately
9.99 years
<h3><u><em>
Answer:</em></u></h3>
x = 15
<h3><u><em>Step-by-step explanation:\</em></u></h3>
Multiply both sides of the equation by 3
3 x 1/3 x X = 3 x 5
Simplify both sides of the equation.
Simplify 3 x 1/3 x X.
1 x X = 3 x 5
Multiply x by 1.
x = 3 x 5
Multiply 3 by 5.
and you get x = 15
