I solved this problem by using a ratio table. I kept doubling the numbers. At 60 litres I found out that in store a it cost 120 dollars for 60 litres. In store B 60 litres cost 108 dollars. In the comparison u will save more money at store b. you will save 20cents per litre if u buy from store b
i found it easier to do a ratio table changing 1.25 and 0.75 to 1 litre and working from there.
you can also see that you pay 2 dollars per litre at store A and you pay slightly less per litre at store B. (to lazy to do the math)
I used a ratio table for my problem.I made the two of the litres equal so I could compare them to see which was the better buy . I did this by dividing.
I did it!!.....lol
yea i used a ratio table too, i got a little confused but i asked my sister, then i got it :)
I did it and i use subtract and division but its hard
i used a table also . i found that at 3.75 litres you can get it at store b for 6.75 . but at store a you get it for 7.50 . i also found another way with algebra .
i got yay!
