Problema Solution
a fraternity $2.00 admission for boys and $1.00 for girls. They made $50.00 and sold 40 tickets. How many girls were there?
Answer provided by our tutors
let 'x' represent the number of girls there, then '40-x' represents the number of boys there
expressed as an equation for cost:
1.00x+2.00(40-x)=50.00
x=30
There were 30 girls there.
