QuestionFind the percent change in beer shipments since 2007 by 2010 using $y=-3.9x+27.3$ . What is $y$ for $x=10$ ?

Studdy Solution

STEP 1

Assumptions1. The percent change in beer shipments can be approximated by the linear equation $y=-3.9x+27.3$ . In this equation, $x=7$ corresponds to the year20073. We need to find the percent change that occurred by the year2010

STEP 2

First, we need to determine the value of $x$ that corresponds to the year2010. Since $x=7$ corresponds to the year2007, we can add to7 to get the value of $x$ for the year2010.
$x =7 +$

STEP 3

Calculate the value of $x$ for the year2010.
$x =7 +3 =10$

STEP 4

Now that we have the value of $x$ for the year2010, we can substitute this into the equation to find the percent change in beer shipments that occurred by2010.
$y = -3.9x +27.3$

STEP 5

Substitute $x=10$ into the equation.
$y = -3.9(10) +27.3$

STEP 6

Calculate the value of $y$ .
$y = -3.9(10) +27.3 =11.$ The percent change in beer shipments since200 that occurred by2010 is $11.\%$ .

QuestionFind the percent change in beer shipments since 2007 by 2010 using y=−3.9x+27.3y=-3.9x+27.3y=−3.9x+27.3. What is yyy for x=10x=10x=10?

Studdy Solution

STEP 1

Assumptions1. The percent change in beer shipments can be approximated by the linear equation y=−3.9x+27.3y=-3.9x+27.3y=−3.9x+27.3 . In this equation, x=7x=7x=7 corresponds to the year20073. We need to find the percent change that occurred by the year2010

STEP 2

First, we need to determine the value of xxx that corresponds to the year2010. Since x=7x=7x=7 corresponds to the year2007, we can add to7 to get the value of xxx for the year2010.x=7+x =7 +x=7+

STEP 3

Calculate the value of xxx for the year2010.x=7+3=10x =7 +3 =10x=7+3=10

STEP 4

Now that we have the value of xxx for the year2010, we can substitute this into the equation to find the percent change in beer shipments that occurred by2010.y=−3.9x+27.3y = -3.9x +27.3y=−3.9x+27.3

STEP 5

Substitute x=10x=10x=10 into the equation.y=−3.9(10)+27.3y = -3.9(10) +27.3y=−3.9(10)+27.3

STEP 6

Calculate the value of yyy.y=−3.9(10)+27.3=11.y = -3.9(10) +27.3 =11.y=−3.9(10)+27.3=11.The percent change in beer shipments since200 that occurred by2010 is 11.%11.\%11.%.
