The increase is 50%
The way I look at it is, 
$1.50 multiplied by 1.5 equals $2.25.
I checked this by doing the following, 
$1.50 divided by 2 equals $0.75, $0.75 multiplied by 3 is $2.25, I also did, 
$2.25 minus $1.50 equals $0.75

Answer:50 percent


Step-by-step explanation:You need to subtract 2.25 and 1.50 and get 0.75 then divide it to 1.5 and 0.5 then convert it into decimal form and its 50%.
