There is 69.147 ML of acid
since we round to the nearest tenth it is 69.1 ML of acid

The expressions (13 + 14) + 11 and 13 + (14 + 11) both demonstrate the associative property of addition. Regardless of how the meals are grouped in the parentheses, the total cost of the meals remains the same at $38.
The question is asking you to create mathematical expressions using parentheses to show the combined cost of three friends' restaurant meals, whose prices are $13, $14, and $11. We can do this by using the associative property of addition, which states that the way in which numbers are grouped when being added does not change the sum.
The first expression could be (13 + 14) + 11, where the meals costing $13 and $14 are grouped together first. The sum of these two meals is $27, so if we then add the $11 meal, we get a total of $38.
The second expression could be 13 + (14 + 11), where the meals costing $14 and $11 are grouped together first. The sum of these two meals is $25, so if we add the $13 meal, we still get a total of $38.
This shows the associative property of addition because regardless of how the meals are grouped in the parentheses, the total cost remains the same.
