IN ORDER TO FIGURE OUT THE ANSWER CHOOSE A NUMBER AND APPLY WHAT IT IS TELLING YOU. FOR EX: on #1: I chose the number 100 then multiplied it by 1.8 then multiplied that number by 0.6 to get 108 which is greater than 100
80% increase followed by 40% decrease=greater
50% decrease follow by 100% increase=greater
20% increase followed by a 25% decrease=less
$25 increase followed by $30 decrease= less
33 1/3% decrease followed by 50% increase= same
