## Elementary Technical Mathematics

First, find the total distance of the side walk in inches. Since 1ft = 12 inches, 30ft = 12 × 30 = 360 inches. Next, find the distance where the daylilies will be planted. They are planted 5 in from each end, so this distance will be: 360-5×2=350 inches. The total number of daylilies can now be found. They are planted 10in apart so the total number of gaps between lilies is $350\div10=35$. The total number of daylilies is found by adding one to this value: 35+1=36.
