Answer:
16
Step-by-step explanation:
8/4 = 2 so each bulb costs $2
To find how many bulbs you can buy with $32, divide 32 by 2 = 16
The irrational in between should be 7.8
divide $4.50 by 5 .......
8 is 1/6 of 8/6 = 1 1/3
125 is 5/10 of 625/10 = 62 1/2
32 is 4/10 of 128/10 = 12 4/5
The answer is B, the x-axis crosses over to -8 the way the line goes also means it is a negative. I don't know for sure because i haven't done this in a while but I hope it helps.
