Solution :
a). Bundles 
= U ( _____ , 2), lie on the same indifference curve. Suppose missing numbers is x.
So, 
(40 x 5) + (2 x 5) = 50x + (2 x 2)
210 - 4 = 5x
So Alexander has 
apples and 
bananas. The indifference curve though also include bundle.
Therefore, (41.2, 2)
b). 
= 0.4
So Alexander has apples and bananas with this bundle. Alexander would like to give up 
unit apples for a banana.
Maybe the adjusted book balance is $45 not sure
Answer:
$8 per direct labor hours and $2 per direct labor hours
Explanation:
The computation of the predetermined overhead rate is shown below:
Predetermined overhead rate = Budgeted fixed manufacturing overhead ÷ planned activity level
= $480,000 ÷ 60,000 direct labor hours
= $8 per direct labor hours
And, the budgeted variable manufacturing overhead is $2 per direct labor hours
We simply divide the budgeted fixed manufacturing overhead by the planned activity level
The answer is b
Overhead are the factory cost which include fixed overhead and variable overhead
