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= ![Original\ price- discount- gift\ card](https://tex.z-dn.net/?f=Original%5C%20price-%20discount-%20gift%5C%20card)
Now, finding the original price of Iphone.
⇒ ![x-0.40x-25= 334.40](https://tex.z-dn.net/?f=x-0.40x-25%3D%20334.40)
⇒ ![0.60x-25= 334.40](https://tex.z-dn.net/?f=0.60x-25%3D%20334.40)
Adding both side by 25
⇒![0.60x= 334.40+25](https://tex.z-dn.net/?f=0.60x%3D%20334.40%2B25)
⇒![0.60x= 359.4](https://tex.z-dn.net/?f=0.60x%3D%20359.4)
Dividing both side by 0.60
⇒ ![x= \frac{359.4}{0.60}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B359.4%7D%7B0.60%7D)
∴ ![x= 599](https://tex.z-dn.net/?f=x%3D%20599)
Hence, the original price of iphone is $599
Answer:
y = 7/8x + 1
Step-by-step explanation:
According to y = mx + b, whereas b is the y-intercept
so if b is positive, b has to be larger than 0
A non-proportional graph is a straight line that does not go through the origin so
The #1 and #4 are wrong because they are proportional
The #2 and #4 are wrong because they have negative y-intercept
About 29%.
35 - 25 = 10, or the amount of change
10 / 35 = .285, or the amount of change over total
I would say the answer is b. It sounds like the best choice
hope i helped!
