Answer:
A scientific calculator costs $3.50 today. I remember when they cost about $75. What is the percent decrease in the price of a scientific calculator?
In other words: The decrease in price is what percent of the original price?
% Decrease= (Decrease in price(New price-Old Price))/(Original Price(old price))×100
Answer:
Step-by-step explanation:
Hello, let's say that the price was P, a real number.
After 20% discount it become P - 20% * P = P* (1-20%) = P * (1 - 0.2)
= P * 0.8
And then we take 15% for the VAT, the new price become P * 0.8 * ( 1 + 15%)
= P * 0.8 * 1.15
And this is equal to 22080, so
P * 0.8 * 1.15 = 22080
and the amount of the VAT is P *0.8 * 0.15
![=\dfrac{22080}{1.15}*0.15=2880](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B22080%7D%7B1.15%7D%2A0.15%3D2880)
Hope this helps.
Thank you.
Answer:
870
Step-by-step explanation:
Assuming you mean
30![P_{2}](https://tex.z-dn.net/?f=P_%7B2%7D)
Using the definition
n
= ![\frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
where n! = n(n - 1)(n - 2) ..... 3 × 2 × 1
Then
30
=
= ![\frac{30(29)(28)(27)...}{28(27)(26).....}](https://tex.z-dn.net/?f=%5Cfrac%7B30%2829%29%2828%29%2827%29...%7D%7B28%2827%29%2826%29.....%7D)
Cancel the terms 28(27)... on numerator/ denominator, leaving
30
= 30 × 29 = 870
