Math Problem: Antra's River Guiding Passengers

Problem: Antra earns €28 per passenger plus a flat €30 tip. Total earnings: €282. How many passengers?

Solution

1. Earnings per passenger: €28 (fee) + €30 (tip) = €58 per passenger.
2. Equation: 58 × x = 282
3. Solve: x = 282 ÷ 58 = 4.862...

Interpretation

Since passengers must be a whole number, the problem implies either:

• Rounding up to 5 passengers (if the tip is per group and the €282 includes partial payment), or
• The numbers are inconsistent—no integer solution exists for €28/passenger + €30 flat tip = €282 total.

Most likely intended answer: 5 passengers (rounding 4.86 up), assuming the tip is per passenger or the total is approximate. If the tip is truly a flat €30 for the whole trip, then (282 − 30) ÷ 28 = 252 ÷ 28 = exactly 9 passengers—a clean integer. The phrasing "28 per passenger and 30 tip" is ambiguous; the flat-tip reading yields a neat answer.
