> determine which options has most positive net value for the lab

$$
\text{Net value}_{\text{Lab}} = \text{Benefits}_{\text{Lab}} - \text{Cost}_{\text{Lab}}
$$

Simulation: gold nanoparticles

$$
\begin{aligned}
    NV_P \text{(relative to purchasing)} &= NV_P - NV_P = 0 \\\
    NV_F \text{(relative to purchasing)} &= NV_F - NV_P = C_P - C_F \\\
    NV_{nR} \text{(relative to purchasing)} &= NV_{nR} - NV_P = C_P - C_{nR} \\\
\end{aligned}
$$

### relative to purchasing

$$
NV = \$896 \, \text{week}^{-1} - \left( \frac{\$5}{100 \, \text{mL}} q_{\text{ingred}} + \frac{\$12.5}{\text{hr}} t_{\text{FumeHood}} + \frac{\$100}{\text{hr}} t_{\text{SEM}} + \frac{\$15}{\text{hr}} t_{\text{GradStudent}} + C_{\text{other}} \right)
$$
