Answer:
To find simple interest you take
= Principal ×Rate ×Time ÷ 100
<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:
2
Step-by-step explanation:
20/2 = 10
4/2 = 2
Equation: <span>3b+4b^2-a^3
Given: </span><span>a=3 & b=-5
Plug 3 in for (a) and -5 in for (b):
</span><span>3(-5)+4(-5)^2-(3)^3
</span>
Now follow PEMDAS:
<span>3(-5) + 4(-5)^2 - (3)^3
</span>-15 + 4(-5)^2 - (3)^3
-15 + 100 - (3)^3
-15 + 100 - 27
85 - 27
58
the asnwer is 58.
32.5* +16* =48.5*
