A customer paid a total of $6.00 for 68 copies at a print shop. Some of the copies were black-and-white copies, and the rest were color copies.

1) Each black-and-white copy cost $0.08.

2) Each color copy cost $0.15.

Which system of equations can be used to find b, the number of black-and-white copies and c, the number of color copies that the customer paid for at the print shop?

• b + c = 6.00

  0.08b + 0.15c = 68

• b + c = 68

  0.15b + 0.08c = 6.00

• b + c = 6.00

  0.15b + 0.08c = 68

• b + c = 68

  0.08b + 0.15c = 6.00

A customer at a store paid $64 for 3 large candles and 4 small candles. At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles. The rice of each large candle is the same, and the price of each small candle is the same.

Which system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y?

• 4y = 3x + 64

  8y = x + 68

• 4y = 3x + 64

  8y = x + 60

• 3x + 4y = 64

  x + 8y = 68

• 3x + 4y = 64

  x + 8y = 60

Nancy went to the grocery story. On Monday she purchased 4 apples and 6 bananas for a total of $13. On Wednesday she purchased 3 apples and 7 bananas for a total of $13.50. Which system of equations represents the situation?

• 4x + 6y = 3

  13.5x - 13y = 6

• x + y = 4

  x - y = 6

• 4x + 6y = 13

  3x + 7y = 13.5

• 4x - 6y = 13

  3x - 7y = 13.5

Amy has only $35. She is going to take a Lyft car downtown. Lyft charges $5 to order the car and $2 per mile. Which inequality shows the maximum number of miles Amy can travel? Let x = number of miles

Carlos works at a movie theater selling tickets. The theater has 300 seats and charges $7.50 for adults and $5.50 for children. The theater expects to make at least $2000 for each showing.

Which systems of inequalities represents this situation?

• x+y≤300

  
  

  7.5x+5.5y≥2000

• x+y<300

  
  

  7.5x+5.5y≥2000

• x+y≤300

  
  

  7.5x+5.5y≤2000

• x+y>2000

  
  

  7.5x+5.5y≤300

• y > 2x - 4
  y < 2
• y < 2x - 4
  y < 2
• y > 2x - 4
  y <  2 
• y < 2x - 4
  y <   -2

A school has 1,200 concert tickets for sale. Some of the tickets are for reserved seats (r), and the rest are for general admission (g). At most, 500 reserved-seat tickets can be sold.
