Correct answer:

x =  100

Step-by-step explanation:

t(125+1x)=1 x+2525x=1t t(x+25)=25x  x=120;t=20.6896551724 x=119;t=20.6597222222 x=118;t=20.6293706294 x=117;t=20.5985915493 x=116;t=20.5673758865 x=115;t=20.5357142857 x=114;t=20.5035971223 x=113;t=20.4710144928 x=112;t=20.4379562044 x=111;t=20.4044117647 x=110;t=20.3703703704 x=109;t=20.3358208955 x=108;t=20.3007518797 x=107;t=20.2651515152 x=106;t=20.2290076336 x=105;t=20.1923076923 x=104;t=20.1550387597 x=103;t=20.1171875 x=102;t=20.0787401575 x=101;t=20.0396825397 x=100;t=20 x=100
