An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $6100 and his stock in Company B was worth $6480. The stock in Company A has decreased 2% since last year and the stock in Company B has decreased 10%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answers
Investment in Company A by investor = $6100
Investment in Company B by investor = $6480
The decrease in value of the stock of company A is 2%
The decrease in value of the stock of company B is 10%
Value of wealth that investor lost in company A = 6100× 2/100
= 61×2
= $122
The decline in the value of the stock of company B = 6480×10/100
= 648×1/1
= $648
The total decline in the wealth of the investor= 122+648
= $770
The combined wealth of investor in both companies= 6100+6480
= $12580
Percentage of decline in the stock account of investor= 770×100/12580
= 77000/12580
= 6.1%
The total percentage decline in investor's stock account is 6.1%

Money is put into two accounts. Account A earns 3.5% interest annually, and account B ears 2.6% interest annually. Assuming $20,000 is split evenly among the accounts and interest is not compounded, how much interest would be earned in total after 6 years?
Answers
Answer:
The total interest earned in both accounts after 6 years would be $2,100 + $1,560 = $3,660.
Step-by-step explanation:
After 6 years, the total interest earned on account A would be:
Interest = Principal x Rate x Time
Interest = $10,000 x 0.035 x 6
Interest = $2,100
The total interest earned on account B would be:
Interest = Principal x Rate x Time
Interest = $10,000 x 0.026 x 6
Interest = $1,560
Therefore, the total interest earned in both accounts after 6 years would be $2,100 + $1,560 = $3,660.

Cell phone company A charges $40 a month, with 500 free minutes and $0.10 a minute after that. Cell phone company B charges $25 a month and all minutes cost $0.05.
Answers
B = 25 + .05M
20 minutes a day for 30 days = 600 minutes per month
A(600) = 40+.1(100) = $50
B(600) = 25 + .05(100) = $30
Plan B is less expensive
40+.1(M-500)= 25+.05M
40-25- .1(500) = .05-.1M
.05M = 35
M= 35/.05 = 700 minutes will have the same cost under plan A or B
40+.1(200) = $60 under plan A
25+.05(700) = $60 under plan B

2x^2-4x+4x-8
2x^2-8
2x^2-8
Answer:
2x^2 - 8
Step-by-step explanation:
You have to take one of the equations and distribute it to the other equation. I'll distribute the 1st equation.
(2x+4)(x-2)
2x times x = 2x^2
2x times -2 = -4x
4 times x = 4x
4 times -2 = -8
So you get 2x^2 - 4x + 4x - 8.
- 4x + 4x cancel out each other
So your final answer is 2x^2 - 8

A small business that makes candles uses a proportional amount of essential oil and wax. For 132 ounces of wax, they use 11 ounces of essential oil.
How many ounces of essential oil is needed for 648 ounces of wax?
A. 54 ounces
B. 58.9 ounces
C. 121 ounces
D. 15.9 ounces
Answers
Answer:
A
Step-by-step explanation:
By proportion, ounces of essential oil for 648 ounces of wax
= 11 * 648/132
= 7128/132
= 54 ounces.
Answer: A - 54 ounces
Step-by-step explanation:
132 divided by 11 ounces = 12
First, you need to figure out the dividend that is giving you the wax-to-oil ratio. Since that is 12, we will divide the new amount of wax by that.
648 divided by 12 = 54
Hope this helps.
