With that particular larcenous scheme in mind, he will price the book
regulaly at
<em>$50</em> . See the price-tag in the attached picture.
With a regular price of
<em>$50</em> written all over it, he can run a spectacular,
once-in-a-blue-moon, "40%-off" sale.
40% of $50 = 0.4 x $50 = $20 off
$20 off of $50 ===> Sale price = <u>$30</u> is what the buyer will pay
during the spectacular sale.
Then, the sale price of $30 is (30/20) = 1.50 of his own original cost.
1.50 of his own cost means 0.50 = 50% more than he paid for it.
Answer:
239.99 x 75%(75/100) $180
$180 x 90%(90/100) = $162
Step-by-step explanation:
Answer:
<h3><em>
Real numbers have two categories: rational and irrational. If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end (non-terminating) and does not repeat a pattern (non-repeating).</em></h3>
Step-by-step explanation:
Step-by-step explanation:
From Trig
1 + tan²x = Sec²x
Also
Sec²x = 1/cos²x
Now
Cot²x = 1/tan²x = cos²x/sin²x
Putting all together
Cot²x(1+tan²x)
= Cot²x(sec²x)
= cos²x/sin²x(1/cos²x)
cos²x on the numerator and that one the denominator cancels out
we have
= 1/sin²x
From Trig
1/sin²x = cosec²x
So Our Answer = cosec²x.
Answer:
The amount is $649.46 and the interest is $49.46.
Step-by-step explanation:
STEP 1: To find amount we use formula:
A=P(1+rn)n⋅t
A = total amount
P = principal or amount of money deposited,
r = annual interest rate
n = number of times compounded per year
t = time in years
In this example we have
P=$600 , r=8% , n=4 and t=1 years
After plugging the given information we have
AAAA=600(1+0.084)4⋅1=600⋅1.024=600⋅1.082432=649.46
STEP 2: To find interest we use formula A=P+I, since A=649.46 and P = 600 we have:
A649.46II=P+I=600+I=649.46−600=49.46
