T=number of tiles bought
cost at store 1 is 0.79t+24
cost at store 2 is 1.19t

when will be equal cost?

0.79t+24=1.19t
minus 0.79t from both sides
24=0.4t
divide both sides by 0.4
60=t

answer is 60 tiles

24 + 0.79t = 1.19t
24 = 1.19t - 0.79t
24 = 0.40t
24/0.40 = t
60 = t

they will be equal at 60 tiles
