Answer: C) (1,0.80) represents the unit rate. E) (25,20) represents the price of a necklace with 25 beads
Step-by-step explanation:
(1, 0.80) represents the unit rate.
(25, 20) represents the price of a necklace with 25 beads.
= unit rate →

Step-by-step explanation:
The response variable is the variable that the researcher is interested in. It is what the experiment really focuses on.
