Question

The relation between the number of gloves(n) and its price(p), is given. The equation that represents the relation is

• A. p = 3n
• B. p = 3n +2
• C. p = 3n + 1

Answer 1

The correct option is B p = 3n +2

From the given table, we observe that

when n = 3, p = 11

$⟹$ p = 3(3) + 2

when n = 6, p = 20

$⟹$ p = 3(6) + 2

when n = 9, p = 29

$⟹$ p = 3(9) + 2

Hence, the relation between n and p, is:

p is the sum of three times n and 2.

Hence, the required equation is p = 3n + 2
