Later 7 students joined group 2 (41 students)and one student left to join group 1. (44 students) Now 20 students play trombone and 7 more students play trumpet as play saxophone. How many students play each instrument?
Trombone=20
Trumpet=15
Saxophone=23
🎲numbers numbers Numbers! 41+7=48
48-20=28 ... I'm sorry! 15+23 isn't 7 more!😮🤐😶
I don't know, I've never had such a hard time with math! This is a nightmare! I hope someone can help me.😢
Grace,Teal,Lynn with all of us I'm sure we'll find it!
To solve this problem, let's break it down step by step:
1. Initially, the number of students in Group 1 is 44, and the number of students in Group 2 is 41. We'll need to determine how many students play each instrument after the given changes.
2. From the information provided, we know that after the changes, Group 1 has 1 more student than Group 2. So, we can conclude that Group 1 has 42 students, and Group 2 has 41 students.
3. According to the last sentence, 20 students play trombone, and 7 more students play trumpet than play saxophone.
Let's denote the number of students playing saxophone as "x". Therefore, the number of students playing trumpet would be "x + 7".
4. We can now add up the number of students playing each instrument to get the total number of students in Group 1:
Number of Trombone players + Number of Trumpet players + Number of Saxophone players = Total number of students in Group 1
20 + (x + 7) + x = 42
Simplifying the equation, we have:
2x + 27 = 42
2x = 15
x = 7.5
Since we can't have half a student playing an instrument, we need to adjust our initial assumption. Let's assume x (the number of students playing saxophone) is 7 instead of 7.5.
Using this new assumption, the number of students playing trumpet would be:
x + 7 = 7 + 7 = 14
Therefore, in Group 1, there are:
- 20 students playing trombone
- 14 students playing trumpet
- 7 students playing saxophone
Please note that the numbers provided assume that each student plays only one instrument.
