100 is grace's initial amount. w is how much of the substance is being decrased each week. in ryan's equation, 1 is 100% of the substance, so the initial amount, and 0.4 is the amount that is being decreased.
Step-by-step explanation:
(x - 4)(x^2 - 5x - 6) =
x(x^2 - 5x - 6) - 4(x^2 - 5x - 6) =
x^3 - 5x^2 - 6x - 4x^2 + 20x + 24 =
x^3 - 9x^2 + 14x + 24 <==
It would take 5 times because if it goes 4 times it would reach 255 miles but if it goes 5 times it will pass the amount.
