Jolly Roger Peanut Butter cost $3.59 for a small jar last year. This year the jar costs $4.19. What is the inflation rate, to the nearest tenth percent?
Answer: 16.7%
I took the k12 unit test
The inflation rate is given by the percentage error and is given by the equation A = 16.71 %
What is Percentage Error?
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage error is the difference between the measured value and the true value , as a percentage of the true value
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Given data ,
Let the inflation rate of percentage error be represented as A
Let the cost of the Jolly Peanut butter be = $ 3.59
So , the original cost = $ 3.59
Let the increased rate of Jolly Peanut butter be = $ 4.19
So , the increased rate = $ 4.19
Now , the inflation rate is given by the equation
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Substituting the values in the equation , we get
Inflation rate A = ( ( 4.19 - 3.59 ) / 3.59 ) x 100
On simplifying the equation , we get
Inflation rate A = ( 0.6 / 3.59 ) x 100
Inflation rate A = 0.16713 x 100
Inflation rate A = 16.71 %
Therefore , the value of A is 16.71 %
Hence , the inflation rate is 16.71 %

Charlotte invests £5000.
The bank pays 10% interest for the first year and then y% every year after that.
After three years, Charlotte has £5610.55
Calculate y
Answer:
y = 1%
Step-by-step explanation:
From the formula;
Interest; i = PRT/100
P = £5000
R = 10%
After 1 year, we have;
i = 5000 × 10 × 1/100 = £500
Amount is now; 5000 + 500 = £5500
Since interest rate is now y% every year after the first one, then;
After 2nd year;
i = (5500 × y × 1)/100
i = 55y
So amount is now;
5500 + 55y
After 3rd year, interest is now;
i = (5500 + 55y) × y × 1/100
i = 55 + 0.55y²
Amount is now;
(5500 + 55y) + (55 + 0.55y²)
Since she has £5610.55 after 3 years, then;
(5500 + 55y) + (55 + 0.55y²) = 5610.55
0.55y² + 55y + 5555 - 5610.55 = 0
0.55y² + 55y - 55.55 = 0
From quadratic formula, y = 1%

Answer:
x=16[tex]\sqrt{\\2\\}[/tex]
y= 16
Step-by-step explanation:
Since we know that this is a right triangle, all sides must add up to 180°. This means that our unknown angle is 45°. With two 45° angles, we know that side y must be 16 (the same as the other corresponding angle). Once we know both legs, we can use Pythagorean Theorem to determine that the hypotenuse, or side x is =16[tex]\sqrt{2}[/tex]

Melissa earns a 2% commission on the first $750 of sales she makes each week. She earns a 3% commission on the amount of her sales that are greater than $750 each week. Melissa earned $37.50 in commissions last week.
Which equations correctly calculate how much money in dollars, x, Melissa made in sales last week?
Select all that apply.
0.02(750)+0.03(750−x)=37.5
0.03(x−750)=37.5−15
15+0.03x−22.5=37.5
0.02(750)+0.03(x−750)=37.5
15−0.03x+22.5=37.5
0.03(750−x)=37.5−15
The equations that are correct are:
0.02(750) + 0.03(x - 750) = 37.5
0.03(750 - x) = 37.5 - 15
Given:
Melissa earns a 2% commission on the first $750 of sales.
She earns a 3% commission on greater than $750 each week.
1. Sales up to $750:
Melissa earns a 2% commission on the first $750 of sales.
=0.02(750)
= 15
2. Sales exceeding $750:
Melissa earns a 3% commission on the amount of sales that exceed $750.
0.03(x - 750) = 37.5 - 15
Combining both equations, we have:
0.02(750) + 0.03(x - 750) = 15 + 37.5 - 15
15 + 0.03x - 22.5 = 37.5
0.03x - 7.5 = 37.5
Adding 7.5 to both sides
0.03x = 45
Dividing both sides by 0.03
x = 1500
Therefore, the correct equations that calculate the amount of money Melissa made in sales last week are:
Equation 1: 0.02(750) + 0.03(x - 750) = 37.5
Equation 2: 0.03(750 - x) = 37.5 - 15

y is a function of x, because for each input x there is only one output y. (It doesn't work backwards. x is not a function of y. not sure if you needed that but there it is!)

You deposit $750 in a bank
account that will earn a simple
interest of 3.5% per year.
How much will your investment
be worth after 12 years?
Answer:
$1,065
Step-by-step explanation:
Simple interest equation: A=P(1+rt)
P (principal amount) = 750, r (rate) = 3.5%, t (time) = 12 years
A=750(1+(3.5)(12))
A=1065
The amount of an investment to be worth after 12 years should be considered as the $1,065
Calculation of an investment:Since
The deposited amount is $750
The rate of interest is 3.5% per year.
And, the time period is 12
So,
A=750(1+(3.5)(12))
A=1065
Hence, The amount of an investment to be worth after 12 years should be considered as the $1,065

Jennifer has one more nickel than she has dimes. If she has $1.25 how many of each type of coin does she have? (HELP IS APPRECIATED)
Answer:
She has 9 nickels, and 8 dimes.
Step-by-step explanation:
We know that she has a total of $1.25. We know that a nickel is $0.05, and that a dime is $0.10.
9x$0.05=$0.45
8x$0.10=$0.80
Answer:
9 nickels
8 dimes
Step-by-step explanation:
.05(n + 1) + .10n = 1.25
.05n + .05 + .10n = 1.25
.15n = 1.20
n = 1.2 / .15
n = 8
but there are 9 nickels because there is "one more nickel than dimes"
