Answer:

See the graph with both lines attached

A) From the tables we see the constant change of values in the second column and the initial value is zero.

  • This represents a proportional relationship.

B) Rate of change is 7 per shirt, the equation is:

  • y = 7x, where y is cost, x - is the number of shirts

C) When x = 20,

  • y = 7*20 = 140
  • Cost of 20 shirts is $140

D) The point (5, 35) represents that:

  • The cost of 5 shirts is $35

E) The second table has confusing titles (not about the number or cost of shirts) but if we assume its same as the first table, then Adidas has greater price of $8 per shirt.

Comparing the prices, Nike has better cost
