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 →
= 0.80;
= 0.80;
= 0.80
Point (1, r) → (1, 0.80) represents the unit rate.
25(0.80) = 20; thus, (25, 20) represents the price of 25 beads.
