Question

There are currently 35 students attending the chess club and that number is increasing

by 3 students a week. There are 20 students attending the ping pong club and that number
is increasing by 1 student a week. Write and solve an equation to determine when the
chess club will have twice the numbers of students as the ping pong club.

Answer 1

28 Students

Explanation:

Let number of students in cooking club = x

Number of students in fencing club = 1/5 x

Number of students in chess club = 2(1/5)x

Since, There are 42 more students in the cooking club than in the chess club

Then ;

Number of students in chess club = Number of students in cooking club - 42

2(1/5)x = x - 42

(2/5)x - x = - 42

(2/5)x - x = - 42

-0.6x = - 42

x = 42 / 0.6

x = 70

Hence, number of students in chess club :

(2/5) * 70 = 28

Hope this helps you!

Good luck!
