Hi there! 5 bottles of water for $3 would make $0.60 per bottle. 0.6 * 15 = 9. That means 15 bottles of water should equal $9, but instead it is $8. Based on that, no. The costs for bottles of water is not proportional to the numbers sold. Basically, you can divide to find unit prices and multiply the number of another item to see if the numbers are proportional.
The answer is 2:3 because it is 12:18 simplified.
Y = 6 + x
We can use this equation to find the total amount of flour that Otto used in the recipe.
The constraints on 'x' and 'y' are that they must both be positive, because we cannot have a negative amount of flour.
<span>And a restraint something like 50 cups of flour total because one person making a recipe won't use that many cups of flour.</span>
