A man buys a book for $20 and wishes to sell it. What price should he mark on it if he wishes for a 40% discount and 50% profit on the cost price. Please explain your answer!

Answers

With that particular larcenous scheme in mind, he will price the book
regulaly at $50 .   See the price-tag in the attached picture.

With a regular price of $50 written all over it, he can run a spectacular,
once-in-a-blue-moon, "40%-off" sale.

   40% of $50 = 0.4 x $50 = $20 off

   $20 off of $50 ===> Sale price = $30 is what the buyer will pay
during the spectacular sale.

Then, the sale price of $30 is (30/20) = 1.50 of his own original cost.

1.50 of his own cost means 0.50 = 50% more than he paid for it.

822 is not prime because you can divide it by 2.
600 is not prime because you can divide it by 10.
743 is prime because you can't divide it by any number.

Step 3: Solve. Show your steps. What is the solution?

Step 4: Check: Also include your check. Does your answer make sense?

Answers

4.50x + 7x= $50.50
you will use Guess and check as a strategy
4.50(5) +7(4) = 50.50

yes the answer does make sense

a - number of nail polish bottles
b - number of lip gloss tubes
a+b=9 => b=9-a
4.50*a+7*b=50.50
4.50*a+7*(9-a)=50.50
4.50*a+63-7a=50.50
63-50.50=7a-4.50a
2.50a=12.50
a=12.50/2.50
a=5 nail polish bottles
b=9-a=9-5
b=4 lip gloss tubes

192 rounded to nearest tenth?

Answers

There is no TENTH in 192 so 192 rounded to the nearest TENTH is 192.

If you meant TEN then 192 rounded to the nearest TEN is 190.

Good Luck!

The next larger tenth is 192.1

The next smaller tenth is 191.9

But 192 is closer to 192 than it is to 192.1 or 191.9, so 192 is ALREADY rounded to the nearest tenth.
