Final answer:
To calculate the number of art club members who voted, multiply the total number of club members (50) by the percentage who voted (80%), resulting in 40 members who voted.
Step-by-step explanation:
The student's question about the art club election is a mathematics problem dealing with percentage calculations. To find out how many members voted, we use the percentage of members who voted and the total number of members in the club. As given, 80% of the 50 members voted in the election. To calculate the number of members who voted, we multiply the total number of members by the percentage that voted:
Number of members who voted = Total members × Percentage of voters
Number of members who voted = 50 × 0.80
Number of members who voted = 40
Therefore, 40 members of the art club cast their vote in the election.
