Answer:
B) $1.25
Explanation:
1. First, let's take two points. In this case, we're going to take (4,5) and (8,10). We took 2 points, so we can verify the unit rate/cost per pound of pineapple.
2. To find the cost per pound of pineapple, we have to divide the cost (the y-coordinates) by the pound (x-coordinates)
- 5 ÷ 4 = 1.25
- 10 ÷ 8 = 1.25
3. Now, since we can verify with 2 coordinates that the cost per pound is $1.25, the answer is B) $1.25.
