Perry is buying an I phone that is a sale for 40% off the original price.after he uses a $25 gift card.the total cost before tax

marta [7]

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= $Original\ price- discount- gift\ card$

Now, finding the original price of Iphone.

⇒ $x-0.40x-25= 334.40$

⇒ $0.60x-25= 334.40$

Adding both side by 25

⇒ $0.60x= 334.40+25$

⇒ $0.60x= 359.4$

Dividing both side by 0.60

⇒ $x= \frac{359.4}{0.60}$

∴ $x= 599$

Hence, the original price of iphone is $599

If there are 2.6 million death per year how many deaths per minute

OlgaM077 [116]

Minutes per year is the main thing to figure out here which takes a tiny bit of multiplying but you'll end up with 525,600 minutes
just divide the deaths per year by minutes per year and it should give you the correct answer
2,600,000/525,600 = 4.95 so if you end up rounding, just about 5 deaths per minute
