Answer:
Step-by-step explanation:
The whole triangle and small triangle are similar (AA). Therefore the sides are in proportion:
<em>cross multiply</em>
<em>use distributive property</em>
<em>subtract 220 from both sides</em>
<em>divide both sides by 55</em>
The correct answer is 6+x-y.
This is because the other answer choice is a binomial and not a trinomial (which contains three terms). A term is always separated by - or + signs.
In order to solve this you need to do the original price - the sold price and figure the difference.
90-180= <span>£</span>18
therefore making it 20% of a profit sale.
