Find out how much you need for one person then multiply by 18 is one way you could do this..
4 divided by 24 = 0.166666666666667 x 18 = 3 litres of lemon-lime soda.
2 divided by 24 = 0.083333333333333 x 18 = 1.5 pints of servet
6 divided by 24 = 0.25 x 18 = 4.5 cups of ice.
Hope this helps!
Your teacher may have wanted you to (some how) use your 6x tables to work this out?!

Hi so if you start at 1.60 and go up by 60% you first look at what 10% of 1.60 is wich is 0.16 then do 0.16 * 6 = 0.96 then do 1.60 + 0.96 = 2.56 then go down by 20% so 10 % is 0.16 and then 20% is 0.32 so then do 2.56 - 0.32 = 2.24 i really have to go now so if you can do the tax part yourself then that would be great!
