A potted sapling loses water through transpiration. If one leaf loses about $2\text{ mL}$ of water in a day, how much water will a sapling with $15$ similar leaves lose over a period of $5$ days?
$30\text{ mL}$
$75\text{ mL}$
$150\text{ mL}$
$300\text{ mL}$
Solution
The total water loss per day for 15 leaves is $2\text{ mL} \times 15 = 30\text{ mL}$. Over 5 days, the total water lost is $30\text{ mL} \times 5 = 150\text{ mL}$.
