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.
