A band sells x premium tickets and y regular tickets for a concert.
• A premium ticket costs $20. • A regular ticket costs $5 less than a premium ticket. • The band raises $2145 from selling tickets. What coefficients would complete the equation representing the relationship between x and y.
___ x + ___ y = 2145
20x + 15y= 2145
