After graduation from college, you will receive a substantial increase in your income from a new job. If you decide that you will purchase more T-bone steak and less hamburger, then for you hamburger would be considered as:
a. complementary good.
b. normal good.
c. inferior good.
d. substitute good.

c. inferior good.

Explanation:

Inferior goods are items purchased buy a consumer as a result of his limited income such that when that consumer's purchasing power increases, he purchases other commodities in place of the one initially purchased.

Hence the  purchase more T-bone steak and less hamburger is an indication that hamburger is an inferior good to the consumer.

Error-less orders = 249 products

Explanation:

Note:

Some data is missing in the question, which is given as follows:

Stage  = 1

%Error = 12%

Stage = 2

%Error = 8%

Stage = 3

%Error = 4%

Step 1:

Find the percentage of error-less products at stage 1:

100% - 12% = 88% of the products will be error-less

Step 2:

Find the percentage of error-less products at stage 2:

100% - 8% = 92% of the products will be error-less.

Step 3:

Find the percentage of error-less products at stage 3:

100% - 4% = 96% of the products will be error-less.

Step 4:

Finding the percentage of over-all product orders:

Multiplying the three percentages determined in the stages 1, 2 and 3

Percentage of over-all error-less product orders = 88% × 92% × 96% = 77.72%

Step 5:

Determine the over-all error-less products by multiplying it with the percentage found in step 4 = 77.72%

Multiply it with the number of products = 320 products

Number of error-less products = 320 products × 77.72% = 248.7 products = 249 products (answer).

The number of error-less products = 249 products.
