Answer:

$98.90

Step-by-step explanation:

Let x = original price in dollars

x is the original price

9% of this original price is equal to 0.09x

subtract: x - 0.09x = 0.91x

The discount price is equal to 0.91x and it's equal to 90 dollars, so they must be the same value.

0.91x = 90

0.91x/0.91 = 90/0.91

x = 98.9010989

x = 98.90

So the original price is $98.90

Using V = lwh, what is an expression for volume of the following rectangular prism? 5/2x+8. 12/x. X+4/4. Answer A.) 15/2x
Svetlanka [38]

Step 1: Substitute the expression for l, w and h in the given volume formula.

l=\frac{5}{2x+8} ;w=\frac{12}{x}; h=\frac{x+4}{4} \\ \\ V=l*w*h\\ \\V=\frac{5}{2x+8} *\frac{12}{x}*\frac{x+4}{4}

Step 2: Simplify the expression by multiplying the fraction.

When multiplying fractions we need to multiply the numerator with numerator and denominator with denominator.

V=\frac{5}{2x+8} *\frac{12}{x} *\frac{x+4}{4} =\frac{5\cdot12\cdot(x+4)}{(2x+8)\cdot x\cdot4}

Factor 2x+8 in the denominator

V=\frac{60(x+4)}{4\cdot x\cdot 2(x+4)}

Cancel the common factors in the numerator and denominator.

V=\frac{15}{2x}

Webster Digital received a promissory note of $8,000 for 9 months at 7% simple interest from one of its customers. After 4 month
podryga [215]
Maturity value is given by

FV=P(1+rt)

where: P is the initial value of the promissory note, r is the simple interest rate, and t is the time period (in years).

Given that <span>Webster Digital received a promissory note of $8,000 for 9 months at 7% simple interest from one of its customers.

P = &8,000; t = 9 months = 9 / 12 = 0.75 years; r = 7% = 0.07

FV=8000(1+(0.07\times0.75)) \\  \\ =8000(1+0.0525)=8000(1.0525) \\  \\ =\$8,420

The proceed from a discounted promisory note is given by

X=FV(1-dt)

where: FV is the maturity value of the promissory note, d is the discount rate and t is the number of years remaining from the time the note was discounted to the maturity date.

Given that </span>a<span>fter 4 months, the note was discounted at Bank of Aventura at a discount rate of 10%.

t = 9 months - 4 months = 5 months = 5 / 12 years; d = 10% = 0.1; FV = $8,420

X=8420\left(1-\left(0.1\times \frac{5}{12} \right)\right) \\  \\ =8420\left(1- \frac{1}{24} \right)=8420\left( \frac{23}{24} \right) \\  \\ =\$8,069.17

Therefore, the proceed is $8,069.17
