bobpursley had this:
Wife's salary = W
Mr T;s salary = 3W  800
then it said: "His wife's salary is 4/10 as much as his" > W = (4/10)T , again as bobpursley told you
but T = 3W800
so
W = (4/10)(3W800)
times 10
10W = 4(3W800)
10W = 12W  3200
3200 = 2W
W = 1600
then T = 3(1600) 800 = 4000
check: is 1600 equal to 4/10 of 4000 ?
