The tables show the cost of different numbers of t-shirts ordered at two different stores, Store A and Store B:
Store A
Number
of T-shirts Cost (in $)
2 $6
4 $12
8 $24
Store B
Number
of T-shirts Cost (in $)
3 $12
6 $24
9 $36
Which of these explains which store has a better buy?
Store A, because the ratio of the number to the cost is 3:1 in Store A and 4:1 in Store B
Store B, because the ratio of the number to the cost is 2:8 in Store A and 3:15 in Store B
Store B, because the ratio of the number to the cost is 8:2 in Store A and 15:3 in Store B
Store A, because the ratio of the number to the cost is 1:3 in Store A and 1:4 in Store B
