Question

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?
A. Store A, because the ratio of the number to the cost is 3:1 in Store A and 4:1 in Store B
B. Store B, because the ratio of the number to the cost is 2:8 in Store A and 3:15 in Store B
C. Store B, because the ratio of the number to the cost is 8:2 in Store A and 15:3 in Store B
D. Store A, because the ratio of the number to the cost is 1:3 in Store A and 1:4 in Store B

Answer 1

To determine which store has a better buy, we compare the ratios of the number of t-shirts to the cost for Store A and Store B. Store A has a better buy because the ratio of the number to the cost is 1:3 in Store A and 1:4 in Store B.

Step-by-step explanation:

In order to determine which store has the better buy, we need to compare the ratio of the number of t-shirts to the cost for both Store A and Store B. Let's calculate the ratios for each store:

Store A: 2 t-shirts for $6, ratio = 2/6 = 1/3

Store B: 3 t-shirts for $12, ratio = 3/12 = 1/4

Comparing the ratios, we can see that Store A has a better buy, because the ratio of the number to the cost is 1:3 in Store A and 1:4 in Store B. Therefore, the answer is D. Store A, because the ratio of the number to the cost is 1:3 in Store A and 1:4 in Store B.
