Derive the equation of the parabola with a focus at (0, 1) and a directrix of y = −1. f(x) = −one fourth x^2
f(x) = one fourth x^2
f(x) = −4x^2
f(x) = 4x^2

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

it is contrapositive
