A consumer is consuming at a point on her budget line. Her income is $50 a week, and she purchases hamburgers and grilled cheese sandwiches. Both goods cost $5 each, and she consumes 10 grilled cheese sandwiches. How many hamburgers does she consume?

0 hamburgers

Explanation:

if the consumer's budget is $50 and each hamburger and cheese sandwich costs $5 each, her consumption possibilities frontier is:

hamburgers                 cheese sandwiches

      10                                        0

       9                                         1

       8                                         2

       7                                         3

       6                                         4

       5                                         5

       4                                         6

       3                                         7

       2                                         8

       1                                          9

       0                                        10

Since she is spending all her money on cheese sandwiches, she doesn't have any money left to spend in hamburgers.

the correct answer would be b, when, queen, calder hall and london.

explanation:

we always capitalize words when a paragraph or sentence is starting, when an important name is used, when a place is being written, or simply when a noun is used, etc. so in this sentence, sentence is starting from 'when', so it will be written in capital letters. secondly, queen is considered to be an important person, so it will also be written in capital letter. next, the name of the town is mentioned, i-e calder hall, which will also be written in capital letters. in the last,   city name is being used, 'london', which will also be written in capital letters. so option b is the most appropriate one.
