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 T-shirts Cost (in $)
3 $18
6 $36
9 $54


Store Q

Number
of T-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 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 to the cost is 3:21 in Store P and 2:12 in Store Q
Store P, because the ratio of the number to the cost is 21:3 in Store P and 12:2 in Store Q

Answer 1

Store Q, because the ratio of the number to the cost is 1:6 in Store P and 1:5 in Store Q.

Answer 2

The answer is the first choice. You can see from the tale that each shirt in Store P costs $6 and in store Q costs $5. That's a ratio of 1 shirt to $6 and 1 shirt to $5 or 1:6, 1:5
