Industrial-strength conveyor belts are made out of a textile fabric core covered with rubber. textile fiber strength is crucial for conveyor belt life. traditionally, "cotton 7s" yarn was the core. however, the new 750 denier polyester yarn is a potential replacement. if the following data hold, what is the maximum amount a conveyor belt manufacturer would be willing to pay for 750 denier polyester to replace cotton 7s yarn? - price of cotton 7s: $ .90/pound- 750 denier polyester yarn is 4 times stronger than cotton 7s.- 750 denier polyester yarn requires an extra $ .30/pound in processing costs.

The manufacturer must be willing to pay 0.6*4 = 2.4$ per pound

Explanation:

As there is extra processing costs of 0.3$ per pound, that needs to deducted from current Price of Cotton.

So, it comes out to be 0.9 $ per pound - 0.3 $ per pound = 0.6$ per pound

Now, as the Polyester yarn is 4 times stronger, the cost needs to be multiplied by the same factor.

Hence, the manufacturer must be willing to pay 0.6*4 = 2.4$ per pound

the answer should be demonstrations i hope this

i believe the answer is: streets and roads
