Question

After 14 boys leave the concert, the ratio of boys to girls is 3 to 10. If 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

Answer 1

let boys:girls=3X:10X
but no. of girls is given, 10X=P
X=P/10
no.of boys=3X
3(P/10)=3P/10
but already 14 left from the concert
=14+(3P/10)
