1. The members of a youth football program are required to sell tickets to chicken dinners for the
program's fundraiser. They can sell adult tickets for $10 and child tickets for $5. Each athlete must
bring in at least $350 from the ticket sales.
a. Write an expression to represent the total amount of money an athlete makes from ticket sales.
Let x represent the number of adult tickets sold and let y represent the number of child tickets sold.
b. Write an inequality in two variables to represent the amount an athlete must make.
C. Graph the inequality from part (b).
d. Use the graph to determine whether an athlete will bring in at least $350 if they sell 10 adult
tickets and 30 child tickets. Explain your reasoning.
2. The quadrilateral ABCD has the vertices A(-5,4), B (0,6), C(1,3), and D(-4,1). Determine whether
it can be classified as a parallelogram. Justify your reasoning.
3. Triangle DEF has the vertices D(-2, 3), E (2, -1), and F(-5, -4). Determine whether it is scalene,
isosceles, or equilateral. Explain your reasoning.
4. Solve for b in the equation ºrzo = 11 – 6a.
