A 10 ft3 tank contains gas at a pressure of 500 psia, temperature of 85 0F and
a mass of 25 lbm. A part of the gas was discharged and the temperature and
pressure changed to 70 0F and 300 psia, respectively. Heat was applied and
the temperature was back to 85 0F. Find the final mass, volume and pressure
of the gas. (15.43 lbm, 10 ft3, 308.5 psia)

Read from the user the maximum number of rolls of toilet paper that may be ordered. Require the maximum number of rools that may be ordered to be an integer from 1 to 10, inclusive. If the user enters a number that is out of range, make them try again until they enter an acceptable number.
Similarly make the user enter the price of one roll of toilet paper as a decimal number of dollars and cents from ten cents(0.10) to three dollars(3.00) inclusive.
Print a table showing the number of rolls in the table for all number of rolls from 1 to the maximum number that the user specified. Each row in the table shows the number of rolls and the price for that number of rolls.
Example:
User enters maximum number of rolls as 48; make them try again.
User enters maximum number of rolls as 4; that is acceptable.
User enters the price per roll as 14.10; make them try again.
User enters the price per roll as -2.70; make them try again.
User enters the price per roll as 0.10; which is acceptable.
