what is the cost in dollars for the nails used to build a fence 125 meters long if it requires 30 nails per meter? Assume that 40 nails are sold per box at a cost of 75 cents per box.

(solve in factor-label method or dimensional analysis)

thanks any help is appreciated

Answer 1

chemistry?

Answer 2

Answer 3

I think this would fit better in the math section :P

Answer 4

Answer 5

Yea but the problem is, this has nothing to do with chemistry

Answer 6

yeah ik its not chem its just preparing you for chem probs that are similat

Answer 7

like units and stuff

Answer 8

should i post it in the math sec

Answer 9

dunno if this calls for a specific way to solve it.
I'd just multiply 125 by 30 and use a crosstable to solve for the price.
But I assume it can be done in a more efficient way.
