Solving Systems with Cramer's Rule · Exercise 64
Create a system of linear equations to describe the behavior. Then, solve the system for all solutions using Cramer’s Rule.
Three artists performed at a concert venue. The first one charged $15 per ticket, the second artist charged $45 per ticket, and the final one charged $22 per ticket. There were 510 tickets sold, for a total of $12,700. If the first band had 40 more audience members than the second band, how many tickets were sold for each band?
