Elena works at the ticket booth of a local play house. On the opening night of the play, tickets are $10 each. The playhouse has already sold $300 worth of tickets during a presale. How many tickets must Elena sell In order for the play house to make a total of $900?

Elena must sell 90 tickets to earn $900

Step-by-step explanation:

Divide the total money needed by how much each ticket costs:

900 ÷ 10 = 90

If you're talking about how many more tickets are needed:

Subtract the total tickets needed by how many tickets Elena already sold

90 - 30 = 60 more tickets needed

I hope this helped!

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
