A company’s profit at the end of the year was -$98.75. Which of these statements must be true?
Hitman42 [59]
The company lost a little less than $100.

Since the number is negative, we know that they lost money. If it was positive, it would've indicated they made money. If they made no money, they would've broken even. This narrows it down to the last two. Since 98 < 100, we know they lost less than $100, which leaves us with the last one.

olga_2 [115]

Answer:
