Amount of wood needed to make a frame = 4(2/3) feet = 14/3 feet
Amount of wood needed to make 4 frames = (14/3)*4 = 56/3 feet = 56/9 yards (since 3 feet is 1 yard) = 6.2 yards
Wood is sold at $5 a yard (and only by the yard so you cannot buy 0.2 yard). So he will need to buy 7 yards.
Total cost = 5*7 = $35
Answer (D)
