Avocado farmers use the percent of dry matter, the matter left after dehydration, from sample avocados in their orchards to determine the best time to harvest the avocados. If a sample of the flesh of the avocado weighs $10$ grams (g) before dehydration, and $1.8 \mathrm{~g}$ after dehydration, what was the percent of dry matter in the sample? (Ignore the $\%$ sign when entering your answer. For example, if the answer is $12 \%$ , enter $12$ .)

Q. Avocado farmers use the percent of dry matter, the matter left after dehydration, from sample avocados in their orchards to determine the best time to harvest the avocados. If a sample of the flesh of the avocado weighs

10

grams (g) before dehydration, and

1.8 \mathrm{~g}

after dehydration, what was the percent of dry matter in the sample? (Ignore the

\%

sign when entering your answer. For example, if the answer is

12 \%

, enter

12

Given Information: We know: $\newline$ Initial weight of avocado flesh: $10\text{g}$ $\newline$ Weight after dehydration: $1.8\text{g}$ $\newline$ To find the percent of dry matter, we need to calculate the ratio of the dry weight to the initial weight and then convert it to a percentage. $\newline$ Calculation: Percent of dry matter = $(\text{Weight after dehydration} / \text{Initial weight}) \times 100$ $\newline$ = $(1.8\text{g} / 10\text{g}) \times 100$ $\newline$ = $0.18 \times 100$ $\newline$ = $18\%$
