Weight of potatoes........Cost
12 lb ................................. $17
18 lb ................................. X
by cross multiplication we get
12 X = 17 × 18
12 X = 306
X = 306/12
X = $ 25.5
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
