a dump truck weighs 11.25 tons when empty a conveyor belt pours sand into the truck at a constant rate of 1/4 ton per minute until it's full. let T represent the elapsed time in minutes. Let W represent the weight of the truck after T minutes.Write an equation for W in terms if TW(T)=________

For this case, the first thing we must do is define variables.
 We have then:
 t: time in minutes
 The linear equation that represents the problem is given by:
 w (t) = (1/4) t + 11.25
 Answer:
 An equation for W in terms if T is:
 w (t) = (1/4) t + 11.25
