Answer:
$698.50
Explanation:
22 posts × $20/post = $440
1 gate × $85/gate = $85
21 pieces of 1.5-m mesh × $5/m = 31.5 m × $5/m = $157.5
1 box of staples × $16/box = $16
(There are 22 posts. Each post uses 5 staples). 5 × 22 = 110. 1 box of staples has 1000 staple, so 1 box is enough.)
$440 + $85 + 157.5 + $16 = $698.50
