A store sells lumber by the linear foot (how long the piece is) based on the cross-section of the piece. For a 4x4 cross section the price is $2 per foot for 8 feet or less. Each foot above 8 feet costs an additional $3 per foot above 8 feet. What is the cost of a piece 20 feet long?

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
