The sum of the digits of a two-digit number is 8. If 16 is added to the original number, the result is 3 times the original number with its digits reversed. Find the original number.

Let x be the first digit and y be the second digit.....so we have......

x + y = 8   (1)

And the original numbe can be represented as 10x + y

And we have

10x + y + 16 =  3(10y + x)

And using (1)   we have that y = 8 - x

So we have

10x + (8 - x) + 16 = 3[10(8-x) + x]

9x + 8  + 16 = 3 [[80 - 10x -+ x]

9x + 24 = 3 [ 80 - 9x ]

9x + 24  = 240 - 27 x     subtract 24 from both sides and add 27x to both sides

36x = 216

So....x = 6     and y = [8 - x ] → [8 - 6]  = 2

So the original number is 62

And adding 16 to this = 78

And this is 3 times the original number with the digits reversed, i. e.,   26 * 3  = 78

Remember, happy7, 6 inches on a side = 36 sq in......but I gave you points for a good effort......

6 square inches on a side = 36 sq in

So, the number of square inches is given by

15 * 12 * 36 = 6480 sq in

And to convert this to square feet, we have

6480 sq in x [ 1 square ft / 144 sq in ] = 45 sq ft.

I'm not a business pro...but I think this means this.....you get a 2% discount if you pay the whole thing witihin 10 days......normally, the net date  would be 20 days after the discount date (May 6), but I believe the "EOM" means that you must pay the whole amount 10 days after the end of the month.....in effect, the EOM extends the "net date" by 4 days

The discount date would be April 16

The net date would be 10 days after the end of the month = May 10

I think this is correct.......

NO..NO.NO.....ammanda ...I ddn't take it like that, at all!!!

Believe me....I took it as a compliment.....!!1

OK....no prob....

Ummmmm....OK

(6 * 4) / 5 =  24 / 5

My answer just "disappeared".......!!!!

Anyway....the answer is 101
