<em><u>Problem One</u></em>
Remark
You don't pay a sales tax until cash is exchanged for goods or services.
So what is 70% off
Solution
Sale price = given price * (100% - 70%)
Sale Price = 72 * 30%
Sale Price = 72 * 30/100
Sale Price = 72 * 0.3
Sale Price = 21.6 dollars.
The sales tax is 5% of this amount
21.6 * 5/100 = 1.08
The total cost is = 21.6 + 1.08 = 22.68
Problem Two
If they marked up 100%, effectively they doubled the price.
New Price = old price + 100% of old price.
New Price = 48.50 + 48.50 = 97 dollars.
The sales tax is 6% * 97 = 6/100 * 97 = 5.82
Total Cost = Cost of item + Tax
Total Cost =97 + 5.82
Total Cost = 102.82 Answer <<<<
Answer:
2/5
8/20
4/10
16/40
Step-by-step explanation:
First of all you have to use the formula
a^2+B^2=c^2
a=6 b=4 c=?
6^2+4^2=?
36+16=?
after you add 36 and 16 find the square root
the square root of 52 is 7.211
if you don't want it in decimals you can just put it like this <span>sqrt(52)</span>
