Solve for u. Enter your answer in the answer box and then click Check Answer.

Lunna [17]

Given that:

$G=\frac{d}{1-u}$

- we cross multiply as follows:

$G\times(1-u)=d$

- we divide both sides by G, as follows:

$\begin{gathered} \frac{G\times(1-u)}{G}=\frac{d}{G} \\ \end{gathered}$ $1-u=\frac{d}{G}$

- Subtract 1 from both sides of the equation:

$1-u-1=\frac{d}{G}-1$ $-u=\frac{d}{G}-1$

- multiply both sides of the equation by -1, as follows:

$-u\times-1=(\frac{d}{G}-1)\times-1$ $u=-\frac{d}{G}+1$

Therefore, we have that:

$u=1-\frac{d}{G}$

or:

$u=\frac{G-d}{G}$

What is the net decimal equivalent of the series 30/25/15. round to the nearest thousandths?

Brut [27]

We can determine, a 30/25/15 series trade discount would be calculated as follows:

let X = retail price.

X - 0.30 × X = Y ⇒ first discounted price.

Y - 0.25 × Y = Z ⇒ second discounted price.

Z - 0.15*Z = T ⇒ total discounted price.

X - 0.30 × X = (1 - 0.30) × X = 0.70 × X = Y

Y - 0.25 × Y = (1 - 0.25) × Y = 0.75 × Y = Z

Z - 0.15 × Z = (1 - 0.15) × Z = 0.85 × Z = T

since Z = 0.85 × Y, then 0.85 × Z = 0.85 × 0.75 × Y

since Y = 0.70 × X, then 0.85 × Z = 0.85 × 0.75 × 0.70 × X

based on the above, then T = total discount

= 0.85 × 0.75 × 0.70 × X

= 0.44625X

30/25/15 series discount is equivalent to a total discount of 44.625%
