Answer:
30 males preferred V-Day, while the other 60 preferred July 4th. 80 females preferred V-day, and 80 females preferred July 4th. I'm sure you can find the totals.
Step-by-step explanation: To begin, you would need to subtract to find the amount of boys that took the survey. 250 - 160 = 90.
The problem says "1/3 of the boys preferred Valentine's day," so you would need to find 1/3 of 90, or 90 / 3, which equals 30.
Since the girls split their votes in half, which would mean 1/2 of 160 girls = 80, then the remaining sections would be 80 for both Valentine's day and July 4th.
