Return on investment is often expressed as follows:

ROI$=\frac{\text{C}\text{o}\text{n}\text{t}\text{r}\text{o}\text{l}\text{l}\text{a}\text{b}\text{l}\text{e}\text{m}\text{a}\text{r}\text{g}\text{i}\text{n}}{\text{A}\text{v}\text{e}\text{r}\text{a}\text{g}\text{e}\text{o}\text{p}\text{e}\text{r}\text{a}\text{t}\text{i}\text{n}\text{g}\text{a}\text{s}\text{s}\text{e}\text{t}\text{s}}=\frac{\text{C}\text{o}\text{n}\text{t}\text{r}\text{o}\text{l}\text{l}\text{a}\text{b}\text{l}\text{e}\text{m}\text{a}\text{r}\text{g}\text{i}\text{n}}{\text{S}\text{a}\text{l}\text{e}\text{s}}\frac{\text{S}\text{a}\text{l}\text{e}\text{s}}{\text{A}\text{v}\text{e}\text{r}\text{a}\text{g}\text{e}\text{o}\text{p}\text{e}\text{r}\text{a}\text{t}\text{i}\text{n}\text{g}\text{a}\text{s}\text{s}\text{e}\text{t}\text{s}}$

Comparative data on three companies operating in the same industry follow. The minimum required ROI is $10\%$ for all three companies. Determine the missing amounts. $($Round asset turnover of Company B and return on investment of Company C to $1$ decimal place, e$.$g$.15\mathrm{.}2$ or $15\mathrm{.}2\%$ and all other answers to $0$ decimal places, e$.$g$.152.$ Enter negative amounts using either a negative sign preceding the number e$.$g$.-45$ or parentheses e$.$g$.(45).)$
