Final answer:
In two weeks, Francine will walk a total of 112 blocks to and from school as she walks to school every day and walks back on every day except for Tuesdays and Thursdays.
Step-by-step explanation:
To calculate how many blocks Francine walks in two weeks, we need to consider the number of school days and the days she is picked up after band practice. Francine walks to and from school every day except on Tuesdays and Thursdays when she only walks to school. We can break down the calculation as follows:
- Days walked per week: 5 days (Monday to Friday)
- One-way distance: 7 blocks
- Days picked up each week: 2 days (Tuesdays and Thursdays)
Walking schedule per week (excluding band practice days):
- Walks to school: 5 days = 5 × 7 blocks = 35 blocks
- Walks back from school (5 days - 2 days picked up): 3 days = 3 × 7 blocks = 21 blocks
Total blocks walked per week: 35 blocks (to school) + 21 blocks (from school) = 56 blocks
Now multiply this by 2 to get the total for two weeks:
56 blocks × 2 weeks = 112 blocks
Therefore, the correct option is D) 112 blocks.
