After 14 boys leave a concert,the ratio of boys to girls is 3:10 there are p girls at the concert,write an algebraic expression for the number of boys at the beginning of the concert in terms of p
There are 10 girls for every 3 boys. Therefore, if we have the number of girls, p, the number of boys is equal to p*(3/10). Then, adding the 14 boys that left, our answer is p*(3/10)+14
