What is the correct mathematical equation: the monthly consumption ,w, of a household is 237 litres per day with an additional monthly free water usage of 1200 litres. the household spends l litres per month is?

Respuesta :

The linear equation for the cost that the household spend in water is given by:

C(d) = 237d + 1200.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For this problem, the free usage of 1200 liters is the y-intercept, while the daily usage of 237 liters is slope. Hence the function for the amount the household spends in water in d days is given as follows:

C(d) = 237d + 1200.
