Question

The table below show the marginal utility, measured in utils, that Ricardo would get by purchasing various amounts of products A, B, C, and D. Column 5 shows the marginal utility Ricardo gets from saving. Assume that the prices of A, B, C, and D are, respectively, $18, $6, $4, and $24 and that Ricardo has a budget of $106.

Quantity of A	MU of A	Quantity of B	MU of B	Quantity of C	MU of C	Quantity of D	MU of D	Number of dollars saved	MU of dollars saved
1	72	1	24	1	15	1	36	1	5
2	54	2	15	2	12	2	30	2	4
3	45	3	12	3	8	3	24	3	3
4	36	4	9	4	7	4	18	4	2
5	27	5	7	5	5	5	13	5	1
6	18	6	5	6	4	6	7	6	0.5
7	15	7	2	7	3.5	7	4	7	0.25
8	12	8	1	8	3	8	2	8	0.125

What quantities of A, B, C, and D will Ricardo purchase in maximizing his utility? How many dollars will Ricardo choose to save?

Derive a demand curve for good A. Show work and explain steps/process.

Consider the following firm, find the missing cost data

Output	Fixed Cost	Variable Cost	Total Cost	Average Fixed Cost	Average Variable Cost	Average Total Cost	Marginal Cost
0	100	0	100	-	-	-	-
1			190
2			270
3			340
4			400
5			470
6			550
7			640
8			750
9			880
10			1030

Answer 1

Refer the attached image

Therefore, number of units of A = 4, B = 3 units, C = 3 units, D = 0, zero unit and Dollar saved = 4.

4 × 18+ 3 × 6 + 3 × 4 + 0 × 24 + 4 = 72 + 18 + 12 + 0 + 4 = $ 106.
