Can someone help me out 10 points

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.

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
