If you solve for dollars per inch, you can multiply that amount by any inches to get the price of any sub. To solve for dollars per inch, use dollars that the equation gives you for a sub. You have 2.95 dollars per 4 inches. This translates to the equation
2.95/4=0.7375
One inch is approximately 0.74 cents. You can multiply 0.7375 by 50 to get the cost of the family sub and then by 12 to get the unit rate in dollars per foot since 1 foot is 12 inches.
0.7375*50=36.875 or approximately $36.88
0.7375*12=8.85 no rounding necessary
Always remember to include units after any number.
