For this, you just need to divide. 6/2=3, 90/2=45, and 100/2= 50. 50+45=95, 95+3=98
Hope this helps!
if I'm correct, 3 would be 78 as well . I'm so sorry if I get this wrong . I struggled a bit with this part and math a lot , and I only worked on it for like 2 days and then I had to test for it
1st find discount
18-13=5
5 is discount
discount from original
5/18=x%
percent means parts out of 100 so x%=x/100
5/18=x/100
multiply both sides by 900
250x=9
divide both sides by 250
x=27.77777
aprox 28%
answer is 28%
