Solutions to Practice Problems

(a) `q=400-5p`

(b) Vertical intercept at `p=80`, horizontal intercept at `q=400`, slope = `- 1/5=-0.2`.

(a) `p=30-1/2 t`

(b) `q=15,000-25p`

(a) `y=5/3 x`

(b) Both intercepts are at the origin: `y=0` and `x=0`. The slope is `5/3`.

(a) `L=(18^2 Q^2)/K`

(b) `m=2 P_x^0.5 P_y^0.5 u`
