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?

Question

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?

Filo · Accepted Answer

N=2.13t2−4.21t+37.40 (Gas spending model)E=−0.209t2+5.393t+307.735 (Electricity speeding models)So, total =E+NSo, total =(2.13t2−4.21t+37.40)+(−0.209t2+5.393t+307.735)Total =1.921t2+1.183t+345.135
