Original price = x
The original price of a pair of shoes was discounted 20%.
20% = 20/100 = 0.2
1 - 0.2 = 0.8
x * 0.8
Now they sell for $54.
x * 0.8 = 54
Solve to find x.
54 / 0.8 = x
x = 67.5
Convert that to currency.
<h2>$67.50</h2>
6 seconds at 20 feet per second is 6x20= 120
She's was at 350 feet so she started at 350-120= 230 feet when she got on the elevator
Step-by-step explanation:
Initial volume is given by,
V = A× h
When the height is increased by 10%, new height i.e h'




Similarly ,when the area of the base reduced by 10%, new area i.e A'


Therefore, new volume V'
V'= A'h'
