Part A = 2 Questions
Part B = 5 Questions
Each A & B are worth 20 points each
10 points x 2 questions = 20
4 points x 5 questions = 20
<h3>
Answer: D) 5.5</h3>
==================================
Work Shown:
MN = x
ML = 6
JN = 8.8
JK = 9.6
----------
Triangle MNJ is similar to triangle LNK, so the corresponding pieces form a proportion as shown below
MN/ML = JN/JK
x/6 = 8.8/9.6 plug in given values
x/6 = 0.91667
x = 6*0.91667 multiply both sides by 6
x = 5.50002
x = 5.5
MN = 5.5
Yolanda's daily salary is $225
Step-by-step explanation:
The given is:
- Yolanda gave 20% of her daily salary to taxes
- She then put 10% of her remaining salary into her savings
- She is left with exactly $162
We need to find Yolanda's daily salary
Assume that Yolanda's daily salary is $x
∵ Yolanda gave 20% of her daily salary to taxes
∵ Yolanda's daily salary is $x
∴ The taxes = 20% × x
∵ 20% = = 0.2
∴ The taxes = 0.2 × x = 0.2 x
∴ The remaining of her salary = x - 0.2 x = 0.8 x
∵ She put 10% of her remaining salary into her savings
∴ The money in her saving = 10% × 0.8 x
∵ 10% = = 0.1
∴ The money in her saving = 0.1 × 0.8 x = 0.08 x
∴ The remaining of her salary = 0.8 x - 0.08 x = 0.72 x
∵ She is left with exactly $162
∴ The remaining of her salary = $162
∵ The remaining of her salary = 0.72 x
- Equate her remaining salary
∴ 0.72 x = 162
- Divide both sides by 0.72
∴ x = 225
Yolanda's daily salary is $225
