A special mixed-nut blend at a store cost $1.35 per lb, and in 2010 the blend cost $1.83 per lb. Let y represent the cost of a pound of the mixed-nut blend x years after 2005. Use a linear equation model to estimate the cost of a pound of the mixed-nut blend in 2007.

y = $1.542 per lb

Step-by-step explanation:

given data

mixed-nut blend store cost  2005 = $1.35 per lb

blend cost in 2010 = $1.83 per lb

solution

we consider here y = cost of a pound

and x year = after 2005

we will use here linear equation model

so

   .........................1

solve it we get

5y - 6.75 = .48 x

so

at 2007 year here x wil be 2

so

solve it we get

y = $1.542 per lb

sine

step-by-step explanation:

range is infinite on both x and y axis positive and negative
