Answer:
4500 cent
Explanation:
From the question, we were told that
a fence 80 meters long requires 30 nails per meter.
1 metre fence = 30 nails
Then 80 meters long= ( 30 × 80)
= 2400 nails
Which means a fence 80 meters long will require 2400 nails in total.
We need to find the cost in dollars for the nails to build a fence 80 meters long.
We know that 40 nails per box will cost 75 cents per box.
(2400 nails/40 nail per box)= 60 box
Then 60 box will be needed to complete the fence.
the cost in dollars for the nails to build a fence 80 meters long= (60 box × 75 cent per box)=4500 cent
