Question

If the equation c = 100 + n, represents the relation between the number of pages(n) and the income (c) for designing websites, the missing values are

• A. 120 and 20
• B. 105 and 10
• C. 100 and 120

Answer 1

The correct option is B 105 and 10

The given equation is c = 100 + n, where n is the number of pages and c is the income.

When number of pages = 5, we get,

c = 100 + 5 = 105

Hence, the income is 105 dollars.

When income = 110 dollars, we get

number of pages is

c = 100 + n

110 = 100 + n

$⟹$ 110 - 100 = n - 100

$⟹$ 10 = n

$⟹$ n = 10

Hence, the number of pages = 10.

Hence, the missing values in the table are 105 and 10.
