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 at the concert? PLZ HELP
Accepted Solution
A:
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
