Let the number of pounds of $1.10 hamburgers be x.

Altogether, this will cost 1.10x -- Total cost of $1.10 hamburgers.

Total cost of $1.80 hamburgers --- 1.80 x 50 = 18 x 5 = $90

Total pounds of hamburgers = (x+50)

Total cost of mixture = 1.30 x (x+50) = 1.30x + 65

So this is our equation:

1.10x + 90 = 1.3x + 65

0.2x = 25

x = 125 pounds
