• On Monday the bus traveled the Green Route 6 times and the Blue Route 5 times, traveling a total of 52 miles.
• On Tuesday the bus traveled the Green Route 12 times and the Blue Route 13 times, traveling a total of 119 miles.

What is the length of the Green Route in miles?

• 4.4 mi

• 4.5 mi

• 6.4 mi

• 6.8 mi

Printer ink costs $18.99 per cartridge. The company that sells the ink cartridges charges a flat rate shipping fee of $7.95, no matter the number of cartridges purchased in a single order. What linear function models the total cost, t, for a single order of c cartridges?

• c = 26.94t

• c = 18.99t + 7.95

• t = 26.94c

• t = 18.99c + 7.95

The graph of a linear function is shown on the grid. Which equation is best represented by this graph?

• y = -7/4x + 4

• y = -7/4x + 7

• y = -4/7x + 4

• y = -4/7x + 7

The tables of ordered pairs represent some points on the graphs of lines f and g. Which system of equations represents lines f and g?

• y = 1.75x + 3.5

  y = -4x - 8

• y = 1.75x + 3.5

  y = -4x - 2

• y = 3.5x + 1.75

  y = -4x - 8

• y = 3.5x + 1.75

  y = -4x - 2

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.

• ⋅ Each black-and-white copy cost $0.08.

• ⋅ 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 new spiral notebook contains 30 more sheets of paper than a new memo book. The total number of sheets of paper in 3 new spiral notebooks and 5 new memo books is 810. Which system of equations can be used to find s, the number of sheets of paper in one new spiral notebook, and m, the number of sheets of paper in one new memo book?

• s - m = 30

  3s + 5m = 810

• s + m = 30

  3s + 5m = 810

• s - m = 30
  5s + 3m = 810

• s + m = 30

  5s + 3m = 810
