A shopper thought shoes marked $40 the sales tax is 8% how much the shopper pay in all

Answers

Answer 1

Answer: so, if I understand correctly the prize before sales tax is 40 dollars and the sales tax is 8%. how much is this?

$(8)/(100) *40= (8)/(10) *4=(4)/(5) *4= (16)/(5) =3.2$

so the final prize is 40+3.2=43.2

A youth group has a yard sale to raise money for a charity. The group earns $800 but decides to put its money in thebank for a while. Calculate the amount of money the group will have given the following scenarios:
c. If the youth group needs the money quickly, which is the better choice? Why?

Answers

Answer: A) $896 b) $927.42 c) Cool bank

Step-by-step explanation:

Cool bank Simple interest is 4% and the youth group leaves the money for 3 years. Therefore,

$800 x (4/100) x (3) = $96 (Interest gotten)

Therefore total funds = $800 + $86 = $896 in total.

Hot bank simple interest is 3% and youth group leaves the money for 5 years. The fore

$800 (1.03)^5 = $927.42

If the youth needs the money quickly, cool bank should be perfect because the bank pays higher interest rate than hot bank. Hot bank rates is better for a longer period of time due to compounding of interest

Which is a solution to (x – 3)(x + 9) = –27?

x = –9
x = –3
x = 0
x = 6

Answers

If you would like to solve (x – 3)(x + 9) = –27, you can do this using the following steps:

(x – 3)(x + 9) = –27
x^2 + 9x - 3x - 27 = -27
x^2 + 6x - 27 + 27 = 0
x^2 + 6x = 0
x * (x + 6) = 0
1. x = 0
2. x = -6

The correct result would be x = 0.

By evaluating the quadraticexpression at each realnumber, we conclude that x = 0 is a solution (root) to (x - 3) · (x + 9) = -27. (Correct choice: C)

How to find the roots of a given polynomic expression

In this question we must find a solution for a polynomicexpression. There are several approaches to find them. Since we have a polynomicexpression as a product of binomials, we can determine the solution by evaluating at each choice:

x = 0

(0 - 3) · (0 + 9) = -27

(-3) · 9 = -27

-27 = -27

By evaluating the quadraticexpression at each realnumber, we conclude that x = 0 is a solution (root) to (x - 3) · (x + 9) = -27. (Correct choice: C)
