The band at charles high school had a concert for charity. They raised $15,000. Adult tickets were $5 each and student tickets were $3 each. The members of the band sold a total of 4,000 tickets. How many student tickets did they sell

Adults =1500 and student= 2500

Step-by-step explanation:

Step one:

GIven data

let Adults be x and student be y in numbers

so

5x+3y=150001

x+y=40002

from 1

x=4000-y, put this in 2, we have

5(4000-y)+3y=15000

20000-5y+3y=15000

-2y=15000-20000

-2y= -5000

2y=5000

divide both sides by 2

y= 2500

put y= 2500 in 2

x+2500= 4000

x= 4000-2500

x=1500

the answer is c)8
