The amount $3. 80 is 4% of what price? a. $7. 80 b. $15. 20 c. $95. 00 d. $97. 20

Answers

Final answer:

The original price for which 4% equals to $3.80 is $95.00 (option c). This was calculated by dividing the given percentage amount ($3.80) by the percentage rate (0.04, which is 4% in the decimal form).

Explanation:

The question is asking us to find out what price $3.80 is 4% of. To answer this, we need to solve for the unknown price, which we'll call 'X'. In the context of this problem, we set up the equation 0.04*X = $3.80. To solve for 'X', we divide $3.80 by 0.04 to find out the original price. Therefore, X equals $95.00, which means that $3.80 is 4% of $95.00. Thus, the answer is c. $95.00.

For which function is the ordered pair (2, 12) not a solution?y = 6x
y = x + 10
y = 14 - x
y = x - 10

Answers

For the equation y = x - 10 the ordered pair (2,12) is not a solution. The correct option is D.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the ordered pair is (2, 12). The equations will be checked as,

For y = 6x

12 = 6 x 2

12 = 12

For y = x+ 10

12 = 2 + 10

12 = 12

For y = 14 - x,

12 = 14 - 2

12 = 12

For y = x - 10,

12 = 2 - 10 = -8

Hence, the equation y = x -10 is not a solution.

Camp Elim obtains a $125,000, 6%, five-year loan for a new camp bus on January 1, 2021. If the monthly payment is $2,416.60, by how much will the carrying value decrease when the first payment is made on January 31, 2021?

Answers

Answer:

The loan amount is = $125000

Rate is = 6%

Term of the loan = 5 years or 60 months

EMI is = $2416.60

Now I have solved this using reducing method ans excel sheet. Please find attached the sheet.

So we can see that after 1st payment, the principle is left to $ 123,208.40

The value decreases by : $125000-123208.40=1791.60$
