A high school chorus has $1000 in its school account at the beginning of the year. They are putting on a fall concert to raise m

oney for a trip later in the year. At the concert last year they sold tickets for $10 each. If they sell tickets at the same price the total amount in the chorus account can be represented by the linear function T = 10x + 1000. If they increase the ticket price to $15, how many tickets will they have to sell to have a total of $4000 in the account?

New equation: T=15x+1000
4000=15x+1000
3000=15x
x=200
200 Tickets.
