The animal shelter is open for 10 hours on Saturday. On Saturday morning, the shelter had 34 dogs. - The shelter gave away 6 dogs to new families during each of the first 4 hours. - The shelter gave away 3 dogs to new families during each of the next 6 hours. - The shelter received 11 new dogs on Saturday In which equation does d represent the number of dogs the shelter had at the end of the day on Saturday?

• d = 34 - (6 x 4) - (3 x 6) + 11

• d = 34 - (6 x 4) - (3 x 6) - 11

• d = 34 - (6 + 4) - (3 + 6) + 11

• d = 34 - (6 + 4) - (3 + 6) - 11
