D. 12 + 13 = 25,
Why you ask? Because the inverse operation of addition is subtraction.
Hope this Helps!!!
The equation is 12x-32=p. p is the perimeter. You would have to work backward and add 32 to p, making the equation now 12x=p+32. Now you have to divide it by 12, so the final expression is x=p+32/12 ( x equals p plus 32 over 12)
what is the question.......
Three would fit cause 3 times 12 is 36 and 4 times 12 is 48 which would be too big
month 4: 13.25*4=53. 53+50 = 103
month 4: 25.75*4 = 103
They both cost $103 on month 4
