Question

currently 96 members participate in the morning workout and this # has been increasing by 2 ppl per week. currently 80 ppl participate in the afternoon workout and this # has been increasing by 3 ppl per week. in how many week will the # of ppl working out in the morning be double the # of ppl working out in the afternoon?

Answer 1

let w represent the number of weeks

so the number of people participating in the morning workout is 96 + 2w

and the number of people in the afternoon workout would be 80 + 3w

make sense?

Answer 2

hmm.... a little..

Answer 3

good enough.

so now.. it says how many weeks for the morning people to be twice of the afternoon people so the equation would be

90 + 2w = 2(80+3w)

solve for w and you're done
