From 2012-2016, the amount (in crores) spent on natural gas N and electricity E by Indian residents can be described by the following expressions, where t is the number of years since 2012.
Gas spending model,
N = $2.13 t^{2} - 4.21 t + 37.40$
Electricity spending model,
E = $- 0.209 t^{2} + 5.393 t + 307.735$
What is the total amount A spent on natural gas and electricity by Indian residents from 2012 to 2016?

1.467 t^{2} + 7.423 + 121.721

1.339 t^{2} - 8.729 t + 76.245

1.01 t^{2} + 7.083 + 97.83

1.921 t^{2} + 1.183 t + 345.135

N = 2.13 t^{2} - 4.21 t + 37.40

(Gas spending model)

E = - 0.209 t^{2} + 5.393 t + 307.735

(Electricity speeding models)

So, total

= E + N

So, total

= (2.13 t^{2} - 4.21 t + 37.40) + (- 0.209 t^{2} + 5.393 t + 307.735)

Total

= 1.921 t^{2} + 1.183 t + 345.135
