Answer:
$599
Step-by-step explanation:
Given: Discount- 40% off on original price.
Gift card= $25
Total cost before taxes is $334.40
Lets assume the original price be "x".
We know there is 40% on original price and Perry uses $25 gift card.
Remember; Total cost= 
Now, finding the original price of Iphone.
⇒ 
⇒ 
Adding both side by 25
⇒
⇒
Dividing both side by 0.60
⇒ 
∴ 
Hence, the original price of iphone is $599
Part A:
Consider from x = -5 to x = -4, they are 1 unit apart and the difference of their outputs is given by:
-3 - (-11) = -3 + 11 = 8.
Thus, the value of the output increases by 8 units for each one unit increase in the input.
Part B:
Consider from x = -3 to x = -1, they are 2 units apart and the difference of their outputs is given by:
21 - 5 = 16.
Thus, the value of the output increases by 16 units for each two units increase in the input.
Part C:
Consider from x = 0 to x = 3, they are 3 units apart and the difference of their outputs is given by:
53 - 29 = 24.
Thus, the value of the output increases by 24 units for each three units increase in the input.
Part D:
It can be noticed that the ratio difference in the outputs to the input intervals are equal for all the given input intervals.
i.e 8 / 1 = 16 / 2 = 24 / 3.
