0.90 = 175% of the original price
X * 1.75 = 0.90
(0.90 / 175) * 100 = $0.51
Hope this helps! :)
Their selling price was 2.45 times the price they bought it. If they split the profit evenly and there was two of them, multiply their profit by two and divide that number by 800 to find how much more they sold it for, so they sold it for 245% more than they bought it
It could be written as 8w the simplified version of the example.
Or you could write it as 2(3w + w) which is 2 time the length and width.
English please ? I only speak English but I’m sure I can help.
