Lourdes wants to put molding around the edge of a rectangular frame that is 8 inches wide and 14 inches long. The molding costs $0.75 per inch. She buys 3 additional inches of molding to be sure she has enough to go around the frame. What is the total cost of molding?

Respuesta :

Perimeter= 2(l+w)
=2(16+8)
= 48inches

48+3 = 51 inches

51 x 0,75 = $38,25
