Of the students attending a school party, 60% of the students are girls, and 40% of the students like to dance. after these students are joined by 20 more boy students, all of whom like to dance, the party is now 58% girls. how many students now at the party like to dance?

There were initially 1,000 students: 600 girls, 400 boys and 400 that like to dance. Now, there are 1,020 students: 600 girls, 420 boys and 420 that like to dance.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Students attending the school party = 60% girls - 40% boys

Students that like to dance = 40%

20 boy students joined the party and all of them like to dance

Now the party = 58% girls - 42% boys

2. How many students now at the party like to dance?

x = Number of students attending the party

Let's calculate the number of students at the party, using the Rule of Three Simple, this way:

Number of students     Percent

x                                       100

20                                       2

x = (100 * 20)/2

x = 2,000/2 = 1,000

There were initially 1,000 students: 600 girls, 400 boys and 400 that like to dance. Now, there are 1,020 students: 600 girls, 420 boys and 420 that like to dance.
