Unit 5 & 6 - Spring Final Exam Review

Wendy's piggy bank contained pennies and nickels. She had $1.03. There were 5 more nickels than pennies. Which system of equations could be used to determine the number of coins she has?

• .01p + .05n = 1.03

  p = n + 5

• 1p + 5n = 1.03

  p = n + 5

• .01p + .05n = 1.03

  n = p + 5

• .01p + .5n = 1.03

  n = p + 5

At a holiday ski resort, skis cost $16 to rent and snowboards cost $19. If 28 people rented on a certain day and the resort brought in $478, which system could be used to determine the number of skis (s) and snowboards (b) rented?

• s+b=478
  19s+16b=28
• s + b = 28
  16s+19b=478
• s+b=478
  16s+19b=28
• s+b=28
  19s+16b=478

Tickets to a movie cost $7.25 for adults and $5.50 for students. A family purchased 8 tickets for $52.75. Which system could be solved to determine the number of adult tickets (a) and student tickets (s) purchased?

• a+s=52.75

  5.5a+7.25s=8

• a + s = 8

  5.5a+7.25s=52.75

• a + s = 52.75

  7.25a+5.5s=8

• a + s = 8

  7.25a+5.5s=52.75

On Monday Joe bought 10 cups of coffee and 5 doughnuts for his office at the cost of $16.50. On Tuesday he bought 5 cups of coffee and 10 doughnuts for a total of $14.25. Which equations could be used to determine the cost of the coffee?

• 10c + 5d = 14.25

  5c + 10d = 16.50

• 10c + 5d = 16.50

  5c + 10d = 14.25

• c + d = 10

  5c + 10d = 16.50

• c + d = 5

  5c + 10d = 16.50
