on March 1, Tessa Obato deposited a check for $9,364.85 in a savings account at state bank. The account pays 4% interest calculated on a daily basis. five days later, on March 6, she withdrew $1,000.00. on March 18, 12 days later, she withdrew $2,000.00. On March 28, 10 days later, she withdrew another $2,000.00. three days later, on March 31, the bank computed interest. how much simple interest did her money earn?
Answers
Her money earned a simple interest of $24.55.
Step-by-step explanation:
Since Tessa deposited $9364.85 and she gets 4% interest on daily basis, then before she withdraws $1000 after 5 days, she must've gotten an interest of:
9364.85 x 4% × (5/365) ≈ 5.13
After withdrawing $1000, she has $8364.85. If this remains in the account for 12days, as we have in the question, then the interest on that will be:
8364.85 x 4% × (12/365) ≈ 11.00
After withdrawing $2000, she has $6364.85. If this remains for 10days, her interest would be:
6364.85 x 4% × (10/365) ≈ 6.98
After withdrawing $2000, she has $4364.85. If this remains for 3days, her interest would be:
4364.85 x 4% × (3/365) ≈ 1.44.
In totality, her interest would be: 5.13 + 11.00 + 6.98 + 1.44 = 24.55.
Hence, her money earned a simple interest of $24.55.

What is exponential regression?
Exponential regression refers to the process of arriving at an equation for the exponential curve that best fits a set of data.
What is the general form of the exponential regression equation?[tex]y =a b^{x}[/tex] is the general form of the exponential regression equation.
Let the exponential regression equation be [tex]y = ab^{x}[/tex].
Taking natural logarithm both the sides of [tex]y = ab^{x}[/tex]
⇒ [tex]ln y = a + x ln b..(i)[/tex]
For the value of a and b substitute the value of y and x from the given table.
substitute, y = 100 and x = 0 in equation (i)
⇒ [tex]ln100= a + 0[/tex]
⇒ a = 4.6
Substitute, y = 15, x = 1 and a = 4.6 in equation (i)
⇒ [tex]ln15 = 4.6 +( 1)lnb[/tex]
⇒[tex]2.7 - 4.6 = lnb[/tex]
⇒[tex]lnb = -1.9[/tex]
⇒ b = [tex]e^{-1.9}[/tex]
⇒ b = 0.149
⇒b = 14.9%
Hence, the value of b indicates 14.9% of the contaminants remains in water after each round of filters.

Let the monthly salary be x
He saves 12 % and that is 17.75
x* 12% = 17.75

x *.12 = 17.17

x*.12 /.12 = 17.75/.12
x =147.91666666

Answer:
The right answer is "3.33333".
Step-by-step explanation:
The given points in the question are:
[tex]P=(7,-3) = (x_1,y_1)[/tex]

what is the slope of the equation -5x + 8y = 30?
Answers
Answer:
The slope is 5/8
Step-by-step explanation:
-5x+8y = 30
Add 5x to each side
8y = 5x+30
Divide by 8
8y/8 = 5/8x+30/8
y = 5/8x + 15/4
This is in slope intercept form y = mx+b where m is the slope and b is the y intercept
The slope is 5/8
Answer: 5/8
Step-by-step explanation:
You would first need to put the equation into standard form. so you add 5x on both sides
Then you divide 8 on both sides
that would give you y=5/8x+3.75
The slope is 5/8

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
A line passes through (-2, 7) and (3, 2). We need to find the slope.
x₁=-2, x₂=3, y₁=7, y₂=2
substitute the values in formula of slope
m=2-7/3-(-2)
m=-5/5=-1
The slope intercept form of line is y=-x+b
To find b put the values of (-2,7)
7=-(-2)+b
7=2+b
7-2=b
5=b
y intercept is 5
Hence the slope of line passing through (-2, 7) and (3, 2). is -1 and the value of the y-intercept b is 5.

A store is having a 20% off sale. The final sale price of the items will include 5% sales tax.
The final sale price of an item can be expressed as 1.05(x – 0.2x), where x is the original price of the item.
Answers
Answer:
0.84 and 84
Step-by-step explanation:
1.05 (x -0.2x) = 1.05 (1-0.2)x = 1.05 * 0.8 x= 0.84x
84% of the original price of item
Answers:
first box = 0.84xsecond box = 84=================================================
Explanation:
Think of x - 0.2x as 1x-0.2x. The numbers out front, the 1 and -0.2, combine to 0.8
The 0.8 converts to 80%, meaning that if there's a 20% off sale, then you still have to pay the remaining 80% of the original price.
The 1.05 indicates that we started with 100%, and then add on 5% sales tax, so 100% + 5% = 1 + 0.05 = 1.05
---------------
Simplifying the expression given to us leads to
1.05(x - 0.2x)
1.05(1x - 0.2x)
1.05(0.8x)
(1.05*0.8)x
0.84x
This shows that the final price, after tax, is 84% of the original price.
