The weekly cost of food for a family of four using the moderate cost plan in the United States increased at a relatively constan
Mila [183]

Answer:

Part a) The weekly cost of food for a family of four in 1997 was $153.09

Part b) y=4.83x+153.09

Part c) \$215.88

Step-by-step explanation:

Part a. What was the weekly cost of food for a family of four in 1997?

Let

y ---->the weekly cost of food for a family of four

x ---> the number of years since 1997

we know that

The linear equation in point slope form is equal to

y-y1=m(x-x1)

In this problem we have a linear function between variable x and variable y

In 2004, the weekly cost of food for a family of four was $186.90

so

In the year 2004

The value of x is equal to

x=2004-1997=7 years

we have

point\ (7,186.90)

m=\$4.83\ per\ year

substitute

y-186.90=4.83(x-7) ----> equation in point slope form

Remember that the year 1997 is when the value of x is equal to zero

so

For x=0

y-186.90=4.83(0-7)

solve for y

y=4.83(-7)+186.90

y=153.09 -----> y-intercept or initial value

therefore

The weekly cost of food for a family of four in 1997 was $153.09

Part b. Write an equation that gives the weekly cost of food for a family of four as a function of the number of years since 1997

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept or initial value

we have

m=\$4.83\ per\ year

b=\$153.09 ----> initial value in 1997

substitute

y=4.83x+153.09

Part c. Find the weekly cost of food for a family of four in 2010 assuming the same rate of increase

In the year 2010

x=2010-1997=13 years

substitute in the linear equation

y=4.83(13)+153.09=215.88
