To find the height of the cactus, make a ratio.
58 inches divided by 4 feet equals x inches divided by 8 feet.
58/4 = x/8
14.5 = x/8
116 = x
The height of the cactus is 116 inches.
I have no idea what did he do
Original price×(1-discount price)=new price or sale price so
Put x in original price...x(1-45/100)=550
So the original price is 1000
