• A variable is a number sentence that can be represented in letters to find
• the same answer.
• For my problem lets say k= 7 and y=10.
•  so my number sentence is[ k*y] + 6.00 = 76 dollars.
•  k*y is the same as 10*7=70 plus 6 dollars equals 76 dollars.

•  so you can use a letter to represent a number.
•  if you have r=80 and t=20 what is your quoteint.
