Final answer:
The linear equation is 15x + 6y = 900. The team needs to sell 25 snacks if they sell 50 tickets to reach the fundraising goal.
Step-by-step explanation:
Linear Equation
The equation that describes the problem can be written as:
15x + 6y = 900
where x represents the number of tickets sold and y represents the number of snacks sold.
Graph
Graphing this equation will result in a line with x-intercept (0, 150) and y-intercept (60, 0).
Finding the Number of Snacks
To find the number of snacks needed to reach the goal, we can use the equation:
15x + 6y = 900
Substituting x = 50 (number of tickets sold), we can solve for y:
15(50) + 6y = 900
750 + 6y = 900
6y = 150
y = 25
Therefore, the team needs to sell 25 snacks to reach the goal.
