Answer:
69×7=60×7+9×7 and if 10×7=70 then 6×70=420 and 9×7=70-7=63
Answer: T = 120 + .15*x
Let T be the total price
Let 'I' be the initial price
Let 'x' be the total number of vertical meters
So, T = I + .15*x
Putting T = 645 and x = 3500 in above equation
we get, I = 120
So, the required equation is
T = 120 + .15*x
