Let the two numbers be x and y Then x + y = 60 And x - y = 2 x = y + 2 Putting the value of x in the first equation we get x + y = 60 y + 2 + y= 60 2y + 2 = 60 2y = 60 - 2 2y = 58 y = 58/2 y = 29 Now putting the value of y in the first equation we get x + y = 60 x + 29 = 60 x = 60 - 29 x = 31 So the value of the two numbers comes out to be 31 and 29. I hope the procedure is clear enough for you to understand.
You can do 1st $12.60 divided by 100 is 0.126 then you do 0.126x10= 1.26 then you add the special price which is $12.60 plus $1.26= $13.86 that is the original price for the dinner.
