Final answer:
To find the number of members present at the church last Sunday, subtract the number of absent members from the total number of members.
Step-by-step explanation:
To find the number of members present at the church last Sunday, we need to subtract the number of absent members from the total number of members. The question states that 16% of the members were absent, so we can calculate this by multiplying 250 by 0.16:
Number of absent members = 250 x 0.16 = 40
To find the number of members present, we subtract the number of absent members from the total number of members:
Number of members present = 250 - 40 = 210
Therefore, there were 210 members present at the church last Sunday.
