At a country concert, the ratio of the number of boys to girls is 2:7. If there are 250 more girls than boys, how many boys are
allsm [11]
We can setup an equation for this.

Boys to Girls = 2:7
Boys =  x
Girls = 250+x
Setup the ratio 
 x:(250+x) = 2:7
x / (250+x) = 2/7
7x = 500+2x
7x-2x = 500
x = 500/5 =100

There are 100 boys at the concert
