Question

The relationship between the number of doghouses (n) and the price (c) is given by the equation, c = 20n. Which of the following options represents the missing values in the table?

• A. 80 and 100
• B. 80 and 120
• C. 100 and 120
• D. 60 and 80

Answer 1

The correct option is B 80 and 120

The relation between number of dog houses and the cost is given by the equation c = 20n

When n = 4, total cost = 20n

$⟹$Total cost= 20 $\times$ 4 = $\$$80

For n =6, we get

Total cost = 20n = 20$\times$6 = $\$$120

Hence, the missing values in the table are 60 and 120 respectively.
