A fence is to be built to enclose a rectangular area of 800 sq. ft.. The fence along three sides costs $6.00 per foot and the fence along the fourth side costs $2.00 per foot. The equations below are for area and cost: A = xy = 800 C = 6(2x + y) + 2y The value of x for the rectangle that will allow the most economical fence to be built is closest to: O 38 O 47 O 23 O 28 O 54
