<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:
(-9.5, 6.75)
Step-by-step explanation:
I inputted both equations on the desmos website and they met at this point
Answer:
A
Step-by-step explanation:
- He spends:
- 30 mins on History
- 60 mins on English
- x mins on math
- so the total time he spends is
- one fourth of this is his math time, since x is math time, then we have
- But we know what totaltime in minutes is so
- or simply:
Answer:
3. Option No. 2:
6x + 2y = 22
3x + 3y = 18
4. Option No. 2:
$2.50
Step by step explanation:
4. 6x + 2y = 22
(3x + 3y = 18) * 2
- Negate
6x + 2y = 22
6x + 6y = 36
2y - 6y = 22 - 36
-4y = -14
y = -14/-4
y = 3.5
An order of onion rings = $3.50
- Substitute to find for x
6x + 2(3.5) = 22
6x + 7 = 22
6x = 22 - 7
6x = 15
x = 15/6
x = 2.5
An order of French fries = $2.50
Is -x^(2)-x+20 an answer choice?
if so its right
