To find last year's profit, we can use the information that this year's profit of $80,000 is 250 percent of last year's profit.
Let last year's profit be represented as \( x \). According to the information given:
\[ 80,000 = 2.5 \times x \]
To solve for \( x \), we can divide both sides of the equation by 2.5:
\[ x = \frac{80,000}{2.5} \]
Calculating that:
\[ x = 32,000 \]
Therefore, last year's profit of Perez's Ski Shop was $32,000.
