Question

The equation y= 1.55x + 110,419 approximates the total cost, in dollars, of raising a child in the United States from birth to 17 years, given the households annual income, x.

Approximately how much would it cost to raise a child from birth to 17 years in a household with an annual income of $48,000?

A. $185,921
B. $184,819
C. $182,419
D. $74,409

Answer 1

Well the equation is y=1.55x+110,419 and they give you X so put that in: y=1.55(48,000)+110,419. Now you multiply: 1.55(48,000)=74,400, y=74,400+110,419. Now add: 74,400+110,419=184,819 or B :)

Answer 2

Option B
`\$184,819`

Explanation:

Let

y------> the total cost in dollars f raising a child in the United States from birth to
`17` years

x------> the households annual income

we have

`y=1.55x+110,419`

Find the value of y for
`x=\$48,000`

`y=1.55(48,000)+110,419=\$184,819`
