Answer:
<em>Thus, the original price of the pair of shoes was $100.</em>
Step-by-step explanation:
<u>Percentages</u>
After a 60% discount, the sale price is now valued at 100-60=40% of its original price.
If the sale price is $40, then the original price is calculated as
$40 / 40 * 100 = $100
Thus, the original price of the pair of shoes was $100.
Verify applying 60% discount:
$100 - 60*$100/100 = $40
40 % off means we pay 60 % (must total 100%)
original price * 60 % = 36.00
change percent to decimal
original price * .6 = 36
divide each side by .6
orginal price = 60
Answer: two equations represent the situation are
y = 3x and y = x + 4
Step-by-step explanation:
The smaller number was represented by x and its values on the x coordinate.
The larger number was represented by y and its values on the y coordinate.
The larger number is equal to 3 times a smaller number. This means that
y = 3x
Also, the sum of the smaller number and 4 is the larger number. This means that
y = x + 4

5,909,999,222-3,999,002,135= 1,910,997,087 which is closest to answer A
Answer:
There are 199 pairs of consecutive natural numbers whose product is less than 40000.
Step-by-step explanation:
We notice that such statement can be translated into this inequation:
Now we solve this inequation to the highest value of 
that satisfy the inequation:
The Quadratic Formula shows that roots are:
Only the first root is valid source to determine the highest possible value of , which is 
. Each natural number represents an element itself and each pair represents an element as a function of the lowest consecutive natural number. Hence, there are 199 pairs of consecutive natural numbers whose product is less than 40000.
