Homer sells tickets for admission to your school play and collects a total of $104. Admission prices are $6 for adults and $4 for children. He sold 21 tickets total. Write a system to represent this situation assuming "a" represents # of adult tickets and "c" represents # of children's tickets.

• a + c = 21
  6a + 4c = 104
• a + c = 104
  6a + 4c = 21
• a + c = 21
  6c + 4a = 104
• a + c = 104
  6c + 4a = 21

Members of the math club launch a model rocket from ground level with an initial velocity of 96 ft/sec.  This can be modeled with the function h(t) = -16t² + 96t.  When does the maximum height occur?

• 6 seconds
• 3 seconds
• 145 seconds
• 160 seconds

When the equation y = 3x + 6 is changed to y = -3x + 6, what effect does this change have on the graph? 

• The line moves to the left on the x-axis.
• The line moves downward on the y-axis.
• The line slants upward, from the left to right, instead of downward. 
• The line slants downward, from left to right, instead of upward.

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step
• They should add 19 instead of subtracting 19
• I can not find an error
• Instead of adding 3k they should subtract 3k
