Step-by-step explanation:

Rational expressions and rational equations can be useful tools for representing real life situations and for finding answers to real problems.

Solve 3/5k-5=7/100 by eliminating the fraction

likoan [24]

I assume you meant to type the following:

3/(5k-5) = 7/100

When we multiply both sides by (100)(5k - 5), we get this:

300 = 7(5k - 5)

300 = 35k - 35

300 - 35 = 35k

265 = 35k

265/35 = k

Kingbird, Inc. purchased merchandise with an invoice price of $3200 and credit terms of 2/9, n/30. Assuming a 360-day year, what

Tatiana [17]

Answer:

80%

Step-by-step explanation:

Data provided as per the question

Number of days in a year = 360 days

Discount provided = 2%

Total net credit period = 30

The calculation of implied annual interest rate inherent in the credit terms is shown below :-

$Inherent\ in\ the\ credit\ terms\ = \frac{Number\ of\ days\ in\ a\ year}{Total\ net\ credit\ period\ - Remaining\ days}\times 2\%$

$Inherent\ in\ the\ credit\ terms\ = \frac{360}{30 - (30\ -\ 9)}\times 2\%$ $Inherent\ in\ the\ credit\ terms\ = \frac{360}{30 - 21}\times 2\%$

$Inherent\ in\ the\ credit\ terms\ = \frac{360}{\ 9}\times 2\%$

$Inherent\ in\ the\ credit\ terms\ = \ 40\times 2\%$

$Inherent\ in\ the\ credit\ terms\ = \ 80\%$

Therefore for computing the inherent in the credit terms we simply applied the above formula.
