the cost in dollars of printing dollar bills when it costs 3.8cents to print a dollar bill

Answer 1

You need to convert 3.8 cents to dollars.

You can observe the pattern for converting cents to dollars by looking at a simpler problem.

How much is 1 cent in dollars? 1 cent = .01 dollars

All we have to do is move the decimal place two to the left to convert cents to dollars.

Remember it's not possible to have less than a penny, so we can't have something like $2.937. You would round to $2.94 in that case. Try to apply the same logic to your problem.

Answer 2

I have to write a function rule to describe this statement...please help

Answer 3

C(x) = .038x
where x is the number of dollar bills printed

That seems too simple, but maybe that's it.
