Invisible braces would cost 5300. I think that’s it. Hope that helped
When an account is rounded off to its nearest dollar will
change based on the place value.
For example, the given account of money if $ 56 730, then it
will be rounded to its nearest ten thousands. Then the given amount will be
rounded to $57,000 in where the given money rounded up and gain up to $300. But
if the money will be rounded with its nearest hundreds, the money will become $
56,700. Notice that the given money rounded down and lost $30 dollars.
It would take 5 because they could do it twice as fast
3 1/4 times 4 is 16 then time 5 1/2 =71.5
