23. Giving a 150% salary raise would mean that your salary is going up by 150% meaning if you have a 46,000 salary, the raise would make it to where your salary is now going to be 69,000. $46,000*150%=69,000 or 46,000*1.5=69000

I believe 19 is wrong but they dont show us answers after its done
I think we have to do the answers our self, now i know that to a lot of people are new to this but it is our only shot. school ends on the 18th and if we don't get this done by then we are goanna get a bad grade. now I'm not a kid who says "STOPS CHEATING" believe it or not I am a veteran of this site, but it's time to do the dangerous thing, the scary thing, the big bad do the assignment on our own.
from my support,
