tip - $9.7
total cost - $58.2
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
Multiply by 6
And
Multiply by 3
eq(1)-eq(2)
Then
