Manuel has already sold $20 worth of tickets to the school play. He has 4 tickets left to sell at $2.50 per ticket. Write a function for the total amount collected from ticket sales

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
