To find out how much money Travis had at the beginning of the day using the work backward strategy, we can follow these steps:
- Start with the amount Travis has at the end of the day: $8 (remaining money).
- Add back the amount he spent on groceries: Since he spent $26 on groceries, we add that back: \[ 8 + 26 = 34 \] So, after groceries, Travis had $34.
- Add back the amount he spent on lunch: He spent $4 on lunch, so we add that back too: \[ 34 + 4 = 38 \]
Thus, Travis had $38 at the beginning of the day.
