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?
Reason slowly and give your answer.
50
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.

.

Therefore, the answer is 50
