Answer:
10 minutes
Step-by-step explanation:
This is somewhat of a trick question and also incomplete.
Assuming he walks his dog 1/6th of an hour each week, he walks his dog 10 minutes per week.
If this is incorrect please tell me the complete question
Option A:
I and III only the answers.
Solution:
Let white vases be "w" and red vases be "r".
Cost of total flower = $336
Cost of each vase = $11
Total cost of the centerpieces
= Cost of (white vases + red vases) + Cost of flowers
= 11(w + r) + 336
= 11w + 11r + 336
Total cost of the centerpieces = 11w + 11r + 336 = 11(w + r) + 336
Therefore I and III only the answers.
Option A is the correct answer.
