I think it is B. and the amount that they each need to pay is $1.13
Well first you have to add common like terms in this case 2r and -6r to get -4r now your equation is -4r+8=40, now subtract 8 from both sides to leave r by itself and get -4r=32, now divide both sides by -4 to get r=-8
Hope this helps

profit : RS 150 and profit % : 3%
Step-by-step explanation:
for profit 10% for loss 4%
s.p will be 2750. s.p will be 2400
Total s.p : 2750 +2400. total s.p : 5150
profit = s.p-c.p. profit%=?
=5150-5000. profit = p /c.p × 100
=150 = 150/5000×100
= 3%
