I think that the answer is $569.8. 550 times 0.072 times 0.5 (half a year) is 19.8, then 550 + 19.8 is 569.8.
Consider, pls, this option:
1) let start price is 'x' and the 1-t increasing is 'y';
2) after the 1-t increasing new1_price is x(y+1);
3) after the 2-d increasing new2_price is 1.25x(y+1);
4) from another side, new2_price is '2x';
5) according to five items it is possible to make up an equation: 1.25x(y+1)=2x;
1.25(y+1)=2, y=8/5 -1=3/5=0.6.
0.6 means 60%.
Answer: 60%.
Distance between two points =
√(3−−2)2+(3−3)2= √52+02= √25+0=
√25= 5
Distance between points (-2, 3) and (3, 3) is 5
