Answer:
From the list of options, Option A is the only correct one:
"the actual usage of materials was less than the standard allowed".
Explanation:
<em>Material usage variance</em>
A material usage variance occurs when the standard quantity required to active a particular level of production is higher or lower than than the actual actual quantity used. A favorable variance would mean than less quantity of materials were used than the standard to achieve a given output level. And an adverse variance would mean the opposite.
<em>Material price variance</em>
A material price variance occurs where materials are purchased at a price either lower or higher than the standard price. A favorable variance is recorded where the actual total cost of materials is lower that the standard cost. While an adverse variance implies the opposite.
From the list of options, Option A is the only correct one
Answer:
interest rate = 5.01%
Explanation:

p0= a = 1000
p1= b = 2400
amount = c= -3623
rate = ?
Because the first amount is investment for a period of 2 years, and the second 1 year, we can solve for rate using the quadratic equation:



A = 1000
B = 2400
C = -3623

x1 = 1.0501111083677623
x2 = -3.4501111083677625
We use the positive root:
x1 = 1.0501111083677623 = (1+r)
1.0501111083677623 - 1 = r = 0.0501111 = 5.01%
EDIT several problems with the math tool but kind of worked
