6 is the square root of 36.
6(6) = 36
Percent means out of 100 so 1%=0.01
so we multiply each decimal with 100 and get the decimal
0.03 times 100=3%
0.3 times 100=30%
0.045 times 100=4.5%
0.49 times 100=49%
10% i believe because it went up by 10 sorry if wrong
I’m pretty sure you can first do 10% at a time which you can round to 13 which is 3 so 3 plus 3 then add tax
