Let pc be pencils, and pn be pens. Then:
5pc+pn=250
pc+2pn=185
Then
10pc+2pn=500
pc+2pn=185
9pc=315
pc=35
pn=75
Pencils are 35 cents; pens are 75 cents

Answer:

$Domain = \{9, 10, 11, 12\}$

$Range = \{22, 32, 41, 30\}$

Step-by-step explanation:

Given

Grade 9: 22

Grade 10: 32

Grade 11: 41

Grade 12: 30

Required

Determine the domain and the range

The domain and range of a function is represented as thus (x,y)

From the given parameters;

$(x,y) = (Grade\ 9, 22), (Grade\ 10, 32) (Grade\ 11, 41), (Grade\ 12, 30)$

Remove "Grade" to represent as only digits

$(x,y) = (9, 22), (10, 32), (11, 41), (12, 30)$

Split to x and y values:

Where x = domain and y = range

$Domain = \{9, 10, 11, 12\}$

$Range = \{22, 32, 41, 30\}$

So, from the list of given options; option C answers the question.
