Question

The equation to present the cost of raising a child 18 years is C=2.42N + 35,000. C is the cost and N represents the income of the parents. The Choys have an income of 60,000 what is their cost of raising a child to 18 years old?

A. 180,200
B. 145,200
C. 156,000
D. 121,000

Answer 1

You just need to replace income (N)'s value:

`C=2.42N+35,000 \\ C=2.42(60,000)+35,000 \\ C=145,200+35,000 \\ C=180,200`

So, answer is A.

Answer 2

Their cost of raising a child to 18 years old is 180,200.

Explanation:

Consider the provided equation.

`C=2.42N + 35,000`

Where, C is the cost and N represents the income of the parents.

The Choys have an income of 60,000 and we need to find their cost of raising a child to 18 years old.

To find the cost, simply substitute the N=60,000 in the above equation and solve for C.

`C=2.42(60,000) + 35,000`

`C=145,200 + 35,000`

`C=180,200`

Hence, their cost of raising a child to 18 years old is 180,200.
