<span>The owner of a automobile repair center purchased new electronic diagnostic equipment for $12000. He paid 10 pERcent down and then paid 60 pAYMENTS monthly of $203.81.
Net loan, P=12000*0.9=10800
Monthly payment, A=203.81
Number of payments, n=60
Let i=APR
A=P(i/12*(1+i/12)^n)/((1+i/12)^n-1)
Substituting values
203.81=10800(i/12*(1+i/12)^60)/((1+i/12)^n-1)
=>
12*203.81/10800=i(1+i/12)^60/((1+i/12)^60-1)
To solve for i, we form the iterative equation:
</span>(1+i/12)^60=(12*203.81/10800)/i*((1+i/12)^60-1)
i=12*(12*203.81/10800*((1+i/12)^60-1)/i)^(1/60-1)
try i=0.05,
f(0.05)=0.05
Therefore the APR is 5%
Answer:
$6400
Step-by-step explanation:
4000x.05=200× 12=2400+4000=$6400
Find the attachment below
A+j=59 so j=59-a
and j=a-3
j=j so
59-a=a-3 subtract a from both sides
59-2a=-3 subtract 59 from both sides
-2a=-62 divide both sides by -2
a=31
n=a=31

We only know the value of <span>f(5)</span>
therefore we need to figure out what we would put in for x in <span>f(<span>1/3 </span>x)</span> to get 5
set
<span><span>1/3 </span>x=5</span><span>x=15
</span>now if <span>x= 15</span> then <span>f(<span>1/3 </span>x)
= f(<span>1/3</span>×15)
= f(5)=8
</span><span>and so
</span><span><span>1/4</span>×8−2=2−1=1
</span>therefore the "corresponding point" is <span><span>(15,1)</span></span>
