Your school's talent show will feature 10 solo acts and 3 ensemble acts. The show will last 90 minutes. The 5 solo performers judged best will give a repeat performance at a second 60 minute show, which will also feature the 3 ensemble acts. Each solo act lasts x minutes, and each ensemble act lasts y minutes. Use this information to answer parts (a) and (b).
a) Write a system of equations to model the situation.
3x+10y = 60
A. 3x + 5y = 90
3x + 10y = 90
B. 3x + 5y = 60
OC. 10x + 3y = 90 5x + 3y = 60
OD. 10x + 3y = 60 5x + 3y = 90
C. 10x + 3y = 90
5x + 3y = 60
