A solar water heater costs about $6240 to install (after rebates). A traditional gas water heater costs about $850 and costs about $320 per year to run. The average annual cost to run the solar water heater is about $75

Create total cost functions for each of the water heaters as a function of the number of years that the heater is used

E1: 6240 + a75 = b
E2: 850 + a320 = b

Answer:

For solar: [tex]S(x)=6240+75x[/tex]

For traditional: [tex]T(y)=850+320y[/tex]

Step-by-step explanation:

Cost to install solar water heater = $6240

The average annual cost to run the solar water heater is about = $75

Total cost to run x years : [tex]S(x)=6240+75x[/tex]

A traditional gas water heater costs about = $850

The average annual cost to run = $320

Total cost to run y years : [tex]T(y)=850+320y[/tex]
