Answer:
n = 19/18
Step-by-step explanation:
11/6 = n + 7/9
-n + 11/6 = 7/9
-n = 7/9 - 11/6
-n = -19/18
n = 19/18
Using weighted average, it is found that she should score 67% on the computer science test.
- The weighted average is given by <u>each proportion multiplied by it's score</u>.
In this problem, the proportions and scores are given by:
- Proportion of 32% = 0.32 for a score of 300.
- Proportion of x for a score of 200.
- Proportion of 46% = 0.46 for a score of 300 + 200 = 500.
Then
She should score 67% on the computer science test.

<h3>
Answer: 17.25 dollars</h3>
=======================================================
Explanation:
15% of 15 = 0.15*15 = 2.25
The cost has increased by $2.25 which means the cost per kilogram is now 15+2.25 = 17.25 dollars
------------
As a slight shortcut, we can multiply the old cost (15) by the multiplier 1.15 to get the same result:
1.15*15 = 17.25
This method allows us to chain together many percentage increases, and it also allows us to include percentage decreases as well. Note how 1.15 is basically the result of 100% + 15% = 1.00+0.15 = 1.15

<h3>What Are Savings?</h3>
Savings are the funds that remain after subtracting a person's consumer spending from their disposable income during a specific time period. Savings, then, is what's left over after all bills and commitments have been fulfilled for an individual or household. Cash or cash equivalents (such as bank deposits) are used to store savings since they carry no danger of loss but also offer very low returns. Savings can increase through investing, but doing so involves putting money at risk.
