Answer 1

The equation to represent 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. If the cost of raising a child to 18 years is $150,000, what is the income of the parents? (Hint: this time you will substitute for C and solve for N.) Round to the nearest dollar.
Answer

$47,521

$6,198

$35,295

$42,843

Answer 2

Given
C = 2.42N + 35,000

Substituting N = $28,700 in the above eq we find:

\[\huge C = 2.42 \times 28700 + 35,000 \]
\[\huge \rightarrow C=69454 +35000 =104454\]

Hence the cost of raising a child to 18 years of age is 104454 dollars.

Thanks that helps alot

Answer 4

Given:

\[\huge C = 2.42N + 35,000.\]
Substituting C = $150,000 in the above eq we find.

\[\huge 150,000 = 2.42N + 35,000\]
\[\huge 150,000 -35000= 2.42N \]
\[\huge 115,000 = 2.42N \rightarrow N = \frac{115000}{2.42}\]
\[N = 47520.66 \approx 47521\]

Hence the income of the parent is 47521 dollars.
