Answer

Explanation:

Step1: Calculate profit per sapling before commission

The profit per sapling before commission is the selling - price minus the growing cost. So, $36.50−15.45 = 21.05$.

Step2: Set up break - even equation

Let the number of saplings sold by Lara, Ian, and Ari be $x$, $y$, and $z$ respectively. The total profit from selling saplings is $(21.05x + 21.05y+21.05z)-(8.15x + 11.25y + 8.90z)-7699.45$. At break - even, this expression equals 0. Simplify it to $(21.05 - 8.15)x+(21.05 - 11.25)y+(21.05 - 8.90)z=7699.45$, or $12.9x + 9.8y+12.15z = 7699.45$.

Step3: Test each option

Option a:

$x = 221$, $y = 191$, $z = 245$ $12.9\times221+9.8\times191 + 12.15\times245$ $=12.9\times221+9.8\times191+12.15\times245$ $=2850.9+1871.8+2976.75$ $=7699.45$

Option b:

$x = 221$, $y = 245$, $z = 191$ $12.9\times221+9.8\times245+12.15\times191$ $=2850.9+2401+2320.65$ $=7572.55\neq7699.45$

Option c:

$x = 191$, $y = 221$, $z = 245$ $12.9\times191+9.8\times221+12.15\times245$ $=2463.9+2165.8+2976.75$ $=7606.45\neq7699.45$

Option d:

$x = 191$, $y = 245$, $z = 221$ $12.9\times191+9.8\times245+12.15\times221$ $=2463.9+2401+2685.15$ $=7549.05\neq7699.45$

Answer:

A. Lara sells 221 saplings; Ian sells 191 saplings; Ari sells 245 saplings
