Due in 20 minutes ! : ( the attendance of your club increased by 30% from last year. there are 195 people in the club now. how many people were in the club last year? ( provide steps )

150 people were in the club last year

Step-by-step explanation:

suppose,

Last year there were x people in the club last year

now,

The attendance of the club increased by 30%  from last year

∴At present the amount of people are in the club =x+(x . 30%)

                                                                                    =x+(x . 30/100)

                                                                                    =x+(30x/100)

                                                                                    = (100x+30x)/100

                                                                                    =130x/100

Given that,

There are 195 people in the club now

∴130x/100=195

=>130x=19500          [multiply both sides by 100]

=>x=19500 /130       [divide both sides by 130]

=>x=150

∴150 people were in the club last year

150

Step-by-step explanation:

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
