a karate club is having a pancake breakfast to raise money for new gym equipment. the graph shows the amount of money that will be raised for different numbers of tickets sold. the club spent $175 on supplies for the breakfast. if 20 tickets have been sold so far, how many more tickets must be sold to cover the cost of supplies? pancake breakfast
Answer
# Explanation:
## Step1: Find the price per ticket
From the graph, when 10 tickets are sold, $50 is raised. So the price per - ticket is $\frac{50}{10}=5$ dollars per ticket.
## Step2: Find the money already raised from 20 tickets
If the price per ticket is $5 and 20 tickets are sold, the money raised is $5\times20 = 100$ dollars.
## Step3: Find the remaining money to cover supplies cost
The cost of supplies is $175$ dollars. The money already raised is $100$ dollars. So the remaining money needed is $175 - 100=75$ dollars.
## Step4: Find the number of additional tickets
Since each ticket costs $5$ dollars, the number of additional tickets needed is $\frac{75}{5}=15$ tickets.
