‼HELP‼

The tables show the cost of different numbers of t-shirts ordered at two different stores, store P and store Q.

Store P:
Number of shirts. Cost (in $)

3. $18
6. $36
9. $54

Store Q:
Number of shirts. Cost (in $)

2. $10
4. $20
8. $40

Which of these explains which store has a better buy❔

○ Store Q, Because the ratio of the number of the number to the cost is 1:6 in store P and 1:5 in Store Q

○ Store Q, Because the ratio of the number to the cost is 6:1 in store P and 5:1 in store Q

○ Store P, Because the ratio of the number of the cost is 3:21 in store P and 2:12 in store Q

○ Store P, Because the ratio of the number of the cost is 21:3 in store P and 12:2 in store Q
