Question

Lena sells earrings from a booth at the arts fair. She pays $\$ 200$ to
rent the booth . She makes $\$ 5$ from each pair of earrings she sells.
Her profit, P, can be found using the following equation

Answer 1

Lena's profit \( P \) can be calculated using the following equation:

\[
P = 5x - 200
\]

Where:
- \( P \) is the profit,
- \( x \) is the number of pairs of earrings sold,
- \( 5x \) represents the total revenue from selling \( x \) pairs of earrings (since she makes \$5 on each pair),
- \( 200 \) is the fixed cost for renting the booth.

This equation shows that her profit is equal to the revenue from sales minus the booth rental cost.
