the concert center sold 11,900 tickets this year, which was 40% more than last year. how many tickets were sold last year

Question

 i need the answer

 

Answer 1

Let x = tickets sold lat year.

 

This year the concert center sold 40% more tickets than last year:  x + 0.40x

 

This year's tickets sold = 11,900  so:

 

x + 0.40x = 11,900 (Combine like terms:  1x + 0.4x)

 

1.4x = 11,900  (Divide both sides of the equation by 1.4 to isolate x)

 

x = 11,900/1.4  (Now you do the division to get the value of x)
