Hope it’s right
Best luck with your studying
So I would first find out when they are equal then do one more than that. 21x=18x+45, 3x=45, x=15 so the answer would be 16 jerseys
3% or 30% I promise you its one of those I have a gut feeling its 30% so go ahead and choose that. I hope this helps.
The answer is 30.
8 x 5 =40
40 - 10 = 30
