Elena is not correct in the two situations.
<h3>What is the effective annual rate?</h3>
Effective annual rate is the interest rate when the effects of compounding is taken account for. In order to determine if Elena is correct, the effective annual rate has to be calculated.
Effective annual rate = (1 + APR / m ) ^m - 1
M = number of compounding
(1 + 0.12 / 12)^12 - 1 = 12.68%
(1 + 0.12 / 2)^2 - 1 = 12.36%

Answer:
Return on investment ≈ 29%
Explanation:
<em><u>using excel function </u></em>
Determine :
Rate = 7% / 12 = 0.0058
Nper value = 30 years * 12 = 360
PV = -$150,000
∴ PMT value = $997.95
next : calculate the outstanding balance 15 years later
= ( 997.95 / 0.00583 ) * ( 1 - ( 1 / ( 1 + 0.00583 )^15*12 ))
= 171174.96 * 0.6489
= $ 111,075.43
<u>Considering the opportunity to refinance </u>
Rate = 6% /12 = 0.005
Nper = 15 * 12 = 180
Pv = - $111,075.43
∴ PMT = 937.32
the monthly saved up payment = PMT 1 - PMT 2
= 997.95 - 937.32 = $60.63
Finally
Rate of return on investment
= 2500 = 60.63 * 
hence Rate of return ≈ 29 %

The research method allows for in-depth feedback and first-hand interaction, but only measures how easy it is to use a product, is the usability study.
<h3 /><h3>What is the Usability Study?</h3>

Answer:
$17,000 favourable
Explanation:
Price variance is the difference between the actual cost incurred to purchase the material and the actual quantity cost on a standard or budgeted rate of the material.As per given data
Actual Quantity = 34,000 gallon
Actual Price = $5.60
Standard cost = $6.1
Total Actual cost = 34,000 x $5.60 = $190,400
Standard cost of Actual purchase = $6.1 x 34,000 = $207,400
Direct-material price variance = Cost at standard rate - Actual Cost = $207,400 - $190,400 = $17,000
The variance is favorable as Oiner Corporation incurred less cost on a quantity purchase than the standard cost of the same quantity.
