- one is the cost; the other is the discount
Step-by-step explanation:
a) As a fraction of the original price Louisa will pay ...
0.85c . . . . 85% of the subscription price
__
b) Louisa's expression (-0.15c) tells the amount of the discount, not the cost of the subscription. If Louisa were to write the cost of the subscription, her expression would be ...
c - 0.15c

The Quadratic<span> Formula uses the "a", "b", and "c" from "ax</span>2<span> + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the </span><span>quadratic equation. Therefore,
</span><span>f(x) = x2 – 5x + 6
a = 1
b = -5
c = 6</span>
3 x $38 = $114
0.08 x $114 = $9.12
$114 + $9.12 = $123.12
