Which strategy would not correctly solve this story problem? Tanya had a dog-walking service during the summer. She took 4 dog walks on Tuesdays and 2 dog walks on Thursdays. How many dog walks did Tanya take after 9 weeks of her dog-walking service?

A.
Make a table.


Week 1 2 3 4 5 6 7 8 9
Total Walks 6 12 18 24 30 36 42


B.
Translate into an equation. 9 × (4 + 2) = d

C.
Draw a diagram. Draw 9 circles. Add 4 + 2 to get the number of dog walks each week (6). Write 6 in each circle. Add the numbers in the circles.

D.
Use logical reasoning. In 1 week Tanya took 4 dog walks on one day and 2 dog walks on another for a total of 6 walks each week. So to figure out the total number of walks, add the number of weeks (9) to the number of walks each week.

i believe either a or c is incorrect because with A the total number of walks would have to continue all of the way until 54. And i dont completely understand C. The wrong one i think is C.
