Eight years ago, Rudi thought that he was making a sound investment by buying $1000 worth of Pro Sports Management stock. Unfortunately, his investment depreciated steadily, losing 15% of its value each year. Which equation models the value of the stock now?

• y = 1000(1.15)^x
• y = 1000(.15)^x
• y = 1000(.85)^x
• y = 8(.15)^x

Which system of equations represents the situation:
Katy weighs 105 pounds and is gaining 2 pounds a month. James weighs 175 pounds and is losing 3 pounds a month. (Let w = weight, m = number of months)

• w = 2m +105
  w = -3m +175
• w = 2m + 105
  w = 3m + 175
• 2m + 3w = 280
  m + w = -1

Which system of equations represents the situation:
An adult ticket at a theme park costs $24.95 and a child’s ticket costs $15.95. A group of 10 people paid $186.50 to enter the park.

• 24.95a + 15.95c = 186.50
  24.95a + 15.95c = 10
• 24.95a + 15.95c = 186.50
  a + c = 10
• a + c = 186.50
  24.95a + 15.95c = 10
• Not enough information
