Label the dimensions l and w, and write down a area and cost equation using the area and prices given. One of the equations is a constraint equation (used to eliminate one of 2 variables) and one is an optimization equation, containing the variable to be optimized. Indicate which is which, then use the constraint equation to eliminate a variable from the optimization equation. Explain and perform the TI-84 steps to find the dimensions and the minimum cost. Include TI-84 screenshots for each step. 1 2 3 4 5 6 7
