4. A shipping crate has a square base with sides of length x feet, and it is half as tall as it is wide. If the material for the bottom and sides of the box costs \$2.00 per square foot and the material for the top costs \$1.50 per square foot, express the total cost of material for the box as a function of x.

• Algebra -

c = 2(x^2 + 4*x(x/2)) + 1.50x^2 = 15/2 x^2
