Three friends arrive at a party their arrival increases the number of people at the party by 20% in total how many people are now at the party

The number of people at the party now is 18.

The percentage of a number is the fraction of that number multiplied by 100. Percentages are represented with this sign: %.

3 friends arrive at a party. The percentage of people increase by 20%.This can be represented with this equation:

p x 20% = 3 people

where p is the number of people at the party before the friends arrived.

p = 3 / 20%

p = 3 / 0.20

p = 15 people

The total number of people at the party now : 15 + 3 = 18.

18 people

Step-by-step explanation:

Let the number of people at the party before the arrival be x

20% of x = 3

20/100 * x = 3

20x = 300

x = 300/20

x = 15

Adding the friends , we have 15 + 3 = 18
