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.
Pn = P0(1+r)∧n
Pnis future value of P0
P0 is original amount invested
r is the rate of interest
n is the number of compounding periods (years, months, etc.)
P(n) = 2250(1+(.03/4)∧8
** since the interest is compounding quarterly, you need to divide the rate by 4, the number of quarters in a year.
Then you would do the math.
