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.
