Fairy Tale Bonus Math Challenge

Once upon a time there were three bears. The Papa bear was the oldest. He was 39 years old. Then there was Mama bear. She was 36 years old. The third bear was their son Andrew. He was 5 years old.
Every day Papa bear would leave for work at 7:00 in the morning and he would get home at 5:00 in the afternoon. He always kissed Mama and Benjamin before he left.
While Papa was gone, Mama and Benjamin were very busy. Benjamin and Mama worked on math problems from 7:00 to 7:45 each morning. Then they went to the grocery store and bought porridge for $1.73. They gave the cashier $2.00.
After they arrived home at 8:35, Mama set the timer for a 15 minute clean-up. After they “blessed” their home, they continued with their school work.
Benjamin helped mama cook dinner. The recipe needed 1 cup of milk, ½ a cup of sugar and 2 cups of flour.
The bears had a busy day, but lived happily ever after!
