  Tables 3 and 5

Step-by-step explanation:

The unit rate in each case can be found by dividing the first y-value by the first x-value.

Table 1: 4/3 ≈ 1.333

Table 2: 4/5 = 0.800

Table 3: 18/31 ≈ 0.581

Table 4: 11/18 ≈ 0.611

Table 5: 7/12 ≈ 0.583

The equation has a "unit rate" of 3/5 = 0.600. The tables with lower rates are ...

  Table 3 and Table 5

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
