Answer:
138 packs
Step-by-step explanation:
Marcello thinks it better to have more water balloons on hand that he actually needs fo the water balloon fight, so he rounds up the number of balloons needed to 276 from 275.
Then he divides 276 by 2, obtaining 138. He needs to buy 138 packets of balloons. This way, he will have acquired the required 275 balloons plus 1 left over.
World Bank's threshold for poverty is $1.25 per person per day.
For a family of four this gives:
Daily income = (number of people) * threshold
Daily income = 4 * $1.25
Daily income = $5
For a year this is:
Yearly income = (daily income) *365
Yearly income = $5 *365
Yearly income = $1825
U.S. poverty threshold is set at $29000. Portion of threshold can be calculated as:

The poverty threshold measured by World Bank is 6.29% of the U.S. poverty threshold.
The required number is 6C4 = 15.
