To determine how many more tickets need to be sold, we first need to find out how much money has already been raised from the 20 tickets sold.
Assuming you have a graph or formula that describes how much money is raised per ticket, you would typically calculate:
- The total amount of money raised from selling 20 tickets (let's denote this as \( R(20) \)).
- Then, compare this amount to the cost of supplies, which is $175.
The required condition is:
\[ R(20) + R(x) \geq 175 \]
Where \( R(x) \) is the revenue from selling an additional \( x \) tickets.
Next, you would attribute the revenue per ticket from the graph or data you have and calculate the number of additional tickets needed so that the total revenue equals or exceeds $175.
If we let \( p \) be the price of each ticket, then:
\[ R(20) = 20p \] And the additional revenue needed would be:
\[ 175 - R(20) = 175 - 20p \]
To cover the remaining cost, you'd need to sell enough tickets \( n \) to fulfill:
\[ np \geq 175 - 20p \]
Thus, if you divide both sides by \( p \):
\[ n \geq \frac{175 - 20p}{p} \]
From this, you can calculate \( n \) based on the ticket price \( p \).
If you provide me the ticket price or reference any specific amount from the graph, I can help you compute exactly how many more tickets need to be sold!
