conversations.value: There were 15 males and 10 more girls at the party. Each attendee received 2 cans of soft drinks. If Mary bought several boxes of soft drinks where a box contains 8 cans and is priced at $5 for each box, how much did Mary spend on soft drinks?

conversations.value: There were 10 + 15 = 25 girls in the party.
  So, there were a total of 15 + 25 = 40 attendees.
  40 x 2 = 80 cans of soft drinks are needed.
  So, Mary bought 80/8 = 10 boxes of soft drinks.
  Therefore, Mary spent 10 x $5 = $50 on soft drinks.
