so R offered 44% the what T sold but it"s questioning "what percent less" ? i understand the price is 56% i beg your pardon is 1 - .44 = .56 or 56% however i"m having trouble grasping what it actually method by what percent less . . .

You probably recognize what it method to say the the number $x$ is 12 less than the number $y$: It means $x$ is $y-12$ (which have the right to be check out as y much less 12). Something is p percent much less than $A$ if it"s A much less p percent (of A), or $A-\fracp100A$.

You are watching: The number of television sets sold by store r

Look at the chart "Number that Units marketed as a Percent of variety of Units in Stock":

The number of television sets offered by save R critical month was roughly 50% $(0.5)$ of its variety of television sets in stock, which is: $0.5*40 = 20$.

The variety of television sets offered by keep T last month was approximately 90% $(0.9)$ that its number of television set in stock, i beg your pardon is: 0.9*50 = 45.

And now, the original question is indistinguishable to: "20 is around what percent less than $45$".

To compute A is what percent much less than B, we compute $$\frac\inter-base.netrmdifference\inter-base.netrmbase$$,where difference is B-A (since A is much less than B), and also base is B.

$$\frac45-2045.100\% \approx 55.55 \% \approx 56 \%$$

Well, if A is $x$ percent much less than B, it means $x=\fracB-AB$ or $A = (1-x)\cdot B$.

Basically, you currently figured the end that save R offered 20 TV sets and also store T offered 45 TV sets. Keep T - keep R = The number that keep R sold much less than store T = 25

You desire to division the distinction by the original. 25/45 = .555 or 56%

if save R sold 44% of what save T sold, climate it to be 56% less than the complete sold by T.

20/45 = .44

Imagine, just how much percentage would save R require to increase to offer the same amount as keep T (i.e. 100% that what keep T sold). It would need to rise sales by 56% percent to acquire to 100%.

1-.44 = 56%.

Steve Kass"s prize is sufficient, but that is exactly how I currently see it.
