Minny has two coupons, but can use one of them. The first one is for $5 off an item; the second coupon is for 20% off an item. T

joja [24]

Let's first solve for the $5 off coupon,

$28 - 5 = 23$

The final total is $23.00 with $5 off.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Now for the final price of the 20% off coupon,

$20\% = 0.2$

0.2 or 0.20 is decimal form of 20%. Easier to multiply than in percent form!

$0.2 \times 28 = 5.6$

$5.6 or $5.60 is 20% of 28, we're not done yet!

Lastly, subtract 20% off of 28 (5.6) from 28,

$28 - 5.6 = 22.4$
$22.4 or $22.40 is the final after 20% off!

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Q. Which is less after the discounts??

$23.00 or $22.40

A. $22.40 of course which was the 20% off.

Part A : Which coupon should she use ?

Answer : Well, to get a lower price, less to pay, the 20% off coupon is better!

Part B: How much money will she save by using the better coupon?

Answer : $5.6 / $5.60 is the amount she'll save!

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

I hope that helps you out!!

Any more questions, please just ask me!!

Eights rooks are placed randomly on a chess board. What is the probability that none of the rooks can capture any of the other r

lbvjy [14]

Answer:

$4.51\times10^{-10}$

Step-by-step explanation:

There are only 2 solutions for none of the rooks can capture any of the other rooks: only if they are laid out in either of the 2 diagonal of the chess board

The number of possible combination for the rock to laid out in 8x8 (64 slots) chess board

$\frac{64 * 63 * 62 * 61 * 60 * 59 * 58 * 57}{8!} = \frac{1.78\times10^{14}}{40320} = 4426165368$ possible combination

So the probability is pretty thin

$P = 2 / 4426165368 = 4.51\times10^{-10}$
