Answer :
Final answer:
The weight decreased from 150 pounds to 135 pounds, indicating a 10% decrease. The correct answer is option B: Decrease.
Explanation:
To determine the percent of change, you calculate the difference between the new value and the original value, then divide that change by the original value, and multiply the result by 100%.
In this case, the weight changed from 150 pounds to 135 pounds. The change in weight is 135 pounds minus 150 pounds, which is -15 pounds. The negative sign indicates a decrease. Now, calculate the percent of change using the formula:
% change = (|Change in value| / Original value) x 100%
= (|-15 pounds| / 150 pounds) x 100%
= (15 / 150) x 100%
= 0.1 x 100%
= 10%
Therefore, there is a 10% decrease in weight. The correct answer is option B: Decrease.
