the row <span>1,5,10,10,5,1</span> is the one we need to expand <span><span><span>(8</span>v+s)</span></span>⁵.

Given <span><span>(a+b)</span></span>⁵ each term of the row is the coefficient of akbt

with k goes form 5 to 0 and t goes from 0 to 5.

A radio is being discounted 20%.if the is sale of the radio is $51.44, what was the original price of the radio?
ehidna [41]
     The Definition of Porcentage is given by:

p= \frac{V_{x}}{V_{t}}
 
     Where Vx is discounted value or increased, and Vt is total value. The discount decreases the "p" value.

p= \frac{V_{x}}{V_{t}} \\ \frac{(100-20)}{100V_{x}} = \frac{1}{V_{t}}  \\ V_{t}= \frac{51.44}{0.8}  \\ \boxed {V_{x}=64.3}

If you notice any mistake in my english, please let me know, because i am not native.
