The trade in value of a John deere riding lawnmower can be determined using the function given by T(x)=-300+2400. Here T(x) is the trade in value, in dollars, after x summers of use.
A) what do the numbers -300 and 2400 signify?
B) when will the value of the mower be $1200?
C) what is the domain of T?
Explain steps please!! It helps me understand!!

I think you omitted the "x" in the "-300x" term.
a) -300 is the loss in value per year. 2400 is the original value of the mower.
b) 1200 = -300x + 2400 ==> x = 4 years of use
c) 0 ≤ x ≤ 8 : The equation is not applicable for trade in values before the mower is bought, x < 0 or after the value reaches 0, x > 8

Where is your 'x' variable in your T(x) equation?
