Answer 1

In order to find the answer to this problem you would be doing the following work. So, for every seven cupcakes, you have two pastries.

Therefore, you could get the following chart:

7 Cupcakes:2 Pastries
14 Cupcakes:4 Pastries
21 Cupcakes:6 Pastries
35 Cupcakes:10 Pastries
42 Cupcakes:12 Pastries
49 Cupcakes:14 Pastries
56 Cupcakes:16 Pastries
63 Cupcakes:18 Pastries
70 Cupcakes:20 Pastries
77 Cupcakes:22 Pastries
84 Cupcakes:24 Pastries
91 Cupcakes:26 Pastries
98 Cupcakes:28 Pastries

In order to find the answer to this problem, you must add two pastries for every seven cupcakes you add. Your answer would be D, because that's the only problem with answers that match up to the chart.
