Problem
너 Google Classroom You might need: 囯 Calculator The price of a train ticket consists of an initial fee of \( \$ 5 \) plus a fee of \( \$ 2.75 \) per stop. Julia has \( \$ 21 \) and would like to travel 50 kilometers. She wants to know the largest number of stops she can afford to buy on a ticket. Let \( S \) represent the number of stops that Julia buys. 1) Which inequality describes this scenario? Choose 1 answer: (A) \( 5+2.75 \cdot S \leq 21 \) (B) \( 5+2.75 \cdot S \geq 21 \) (c) \( 5+2.75 \cdot S \leq 50 \) (D) \( 5+2.75 \cdot S \geq 50 \) 2) What is the largest number of stops that Julia can afford? stops Show Calculator
Solution
Step 1 ：\( 5 + 2.75 \cdot S \leq 21 \)
Step 2 ：\( 2.75 \cdot S \leq 16 \)
Step 3 ：\( S \leq \frac{16}{2.75} \approx 5.8182 \)
