Keiran owns a drone and is thinking of adding a camera and starting a business filming with his drone. He decides he needs more information to make a choice of what kind of camera to buy.
He conducts an experiment with his drone. He added weight to the drone and then measured how long the battery life lasted. Below are his results:
Weight Added (grams) Battery Life (seconds)
0 546.6
16 517.3
28 501
36 482.3
54 461.3
78 449.6
86 393.3
94 364.3
106 337.6

Keiran finds two cameras he is considering purchasing. The first camera weighs 58 grams and the second camera weighs 88 grams.
What is the predicted battery life for the first camera?
(Round to two decimal places.)
What is the predicted battery life for the second camera?
(Round to two decimal places.)
How much extra battery life will Keiran have if he buys the lighter camera (camera #1)?
(Round to two decimal places.)
The lighter camera (camera #1) costs $50 more than the heavier camera (camera #2). Which camera do you think Keiran should purchase?
