Answer:
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
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.
