To find out which store charges the least per balloon, we need to calculate the price per balloon at each store.

Parties R Us:
Price: $4.80 for 16 balloons
Price per balloon = $4.80 / 16 = $0.30 per balloon -
Balloon Land:
Price: $3.84 for 12 balloons
Price per balloon = $3.84 / 12 = $0.32 per balloon -
Balloons O Rama:
Price: $3.69 for 9 balloons
Price per balloon = $3.69 / 9 = $0.41 per balloon -
Party World:
