Answer:
Having invested $ 300 per month for the past 8 years, the total accumulated investment amount would be $ 28,800 (8 x 12 x 300). Now, having a total amount of $ 43,262, we find an increase of $ 14,462, which corresponds to the interest accumulated during said period. To know the percentage of the increase, we must perform a cross multiplication:
28,800 = 100
14,462 = X
(14,462 x 100) / 28,800 = X
1,446,200 / 28,800 = X
50.21 = X
As we can see, the investment had an increase of 50.21% during these 8 years. Now, the average increase in investment arises from the division of the total percentage of increase by the number of years. So, given that 50.21 / 8 = 6.27, the average annual return rate of this investment is 6.27%.
Answer:
The change in the dollar amount of inventory is $200 due to change in the inventory costing method.
Explanation:
The variable cost per unit is $6.00 while the fixed cost per unit is $2.00
Variable cost per unit = $6.00
Absorption cost pet units = $8.00
Total cost under absorption costing = Absorption cost per unit / number of units in ending inventory
Total absorption cost = $8.00 × 100 = $800
Total cost under variable cost = Variable cost per unit × number of units in ending inventory
Total variable cost = $6.00 × 100 = $600
Change in cost = Total absorption cost - Total variable cost
Change in cost = $800 - $600 = $200
