Final answer:
Quinn earned a total of $37.20 from dog sitting and recycling cans. A scenario where Quinn ends the week with zero dollars could be if he paid off a $37.20 debt or made a purchase equaling his total earnings.
Step-by-step explanation:
The student asked to find the total amount Quinn earned from dog sitting and recycling cans. To calculate this, we need to add the two amounts together:
- Dog sitting earnings: $24.50
- Recycling cans earnings: $12.70
To find the total, we add:
$24.50 + $12.70 = $37.20
Quinn earned a total of $37.20.
To describe a situation in which Quinn ends the week with zero dollars, suppose he then spends all of his earnings on expenses. For example, he could pay a debt of $37.20 or purchase an item for that exact amount, reducing his total cash to zero.
