Answer:
$37
Step-by-step explanation:
Travis has $8 left in his pocket. Do the opposite of what he did. If he "spent money", add it to the amount he has left. If he "found" money, then subtract.
First, he spent $26 on groceries for dinner. Add 26 with 8:
8 + 26 = 34
He found $1 on the ground. Subtract 1:
34 - 1 = 33
He spent $4 on lunch. Add 4:
33 + 4 = 37
Travis had $37 at the beginning of the day.
