Answer:
"Table 1"
Step-by-step explanation:
The number line given shows that in 1 week, Irene can build 9 model trains.
So the ratio is 1 : 9 [week : train]
Given the table with larger numbers, we have to see which table holds this ratio true.
Table 1:
5 week 45 trains = 45/5 = 9 trains per week
12 week 108 trains = 108/12 = 9 trains per week
26 week 234 trains = 234/26 = 9 trains per week
Table 1 is OK.
Table 2:
90 week 10 trains = 1/9 train per week
126 week 14 trains = 1/9 train per week
315 week 35 train = 1/9 train per week
Table 2 is certainly NOT OK.
Thus, Table 1 represents the correct rate of Irene.
