The original price of the food items was 24.
10 different pairs. Since there are 5 different brands you simply add 4+3+2+1 to get 10.
It is. The reason? I will explain
2:9 is equal to 4:18 because if you multiply both sides by 2, they are 4:18.
So as long as you multiply both sides evenly by the same number, they are equivalent as you see

Get 4:18 and divide both sides by 2
4÷2=2 and 18÷2=9 so it would be 2:9
