Answer:

C = 1200x + 450

Step-by-step explanation:

C = 30y + 15... (1)

y = 40x + 25... (2)

Substituting y = 40x + 25 in equation (1)

C = 30(40x + 25) + 15

C = 30*40x + 30*15

C = 1200x + 450

kvasek [131]

Answer:

Option (A)

Step-by-step explanation:

But the elements in the sets of rational and irrational numbers will be different.

In short, rational and irrational number sets are the two subsets of real numbers.

Hence, the number is an element of either the set of rational numbers or the set of irrational numbers.

Option (A) is the correct option.
