Final answer:
To find the percent of decrease, we divide the decrease by the initial number and multiply by 100.
Step-by-step explanation:
To find the percent of decrease in the number of sand dollars Jose found, we need to compare the initial number of sand dollars to the final number and calculate the difference.
The initial number of sand dollars is 3, and the final number is 2. The decrease is 1 sand dollar.
To find the percent of decrease, we divide the decrease by the initial number and multiply by 100.
Percent decrease = (decrease / initial number) * 100%
Percent decrease = (1 / 3) * 100% = 33.33%
Therefore, the percent of decrease in the number of sand dollars Jose found is 33.33%.
