Answer:
The function is C(t)=20 + $2.50X
Total amount is $30
Step-by-step explanation:
Manuel has already sold $20 worth of tickets to the school play, He has 4 tickets left to sell at $2.50 per ticket
It means he sell 1 ticket for $2.50
Then he sold the $20 worth of tickets to the school play at $2.50 per ticket i.e $20/2.50= 8 tickets which means he sold 8 tickets for $20.
If He has 4 tickets left to sell at $2.50 per ticket
Then he will sell at ($2.50×4)=$10
Then total tickets sold= $10+$20= $30
LET US WRITE THE FUNCTION NOW
The function for the total amount collected from ticket sales can be written as
C(t)=20 + $2.50X
Where X is the number of tickets to be sold
C(t) = total amount
$20= initial sold
If He has 4 tickets left to sell then
C(t)=20 + $2.50(4)
C(t)= 20+10= $30
