1. B (firefighter question) 2. A (dance lesson fee question) 3. A (dolphin question)
Step-by-step explanation:
1. The firefighters gear PLUS his weight is how much he weighs in total.
2. An added fee is usually represented as a registration fee or staring fee. There was 45w which should represent the fee she paid every week.
3. The dolphin swims at a rate of 25 kilometres per hour. The graph represents the distance the dolphin traveled because in two hours the dolphin would travel 50 kilometres (25 kilometres*2 hours) and so on.
