Algebra practice question
A car rental costs $25 per day plus $0.20 per kilometre driven. What is the cost, in dollars, of a one-day rental in which 150 kilometres are driven?
Answer: 55
25 + 0.20 × 150 = 25 + 30 = 55.
Common wrong answers
- If you answered 30
- 30 is the distance charge alone.
- If you answered 175
- 175 adds 150 to 25, treating each kilometre as $1.
- If you answered 3780
- 3,780 multiplies (25 + 0.2) by 150.
