First, I would like to say that the whole question is not here. The question states: upon examining the contents of 38 backpacks, it was found that 23 contained a black pen, 27 contained a blue pen, and 21 contained a pencil, 15 contained both a black pen and a blue pen, 12 contained both a black pen and a pencil, 18 contained both a blue pen and a pencil and 10 contained all three items. How many backpacks contained none of the three writing instruments?
OK I will explain this the best I can!
Starting out, their are 10 backpacks that contain all the items. 12 contained both a black and blue pen. You would subtract 10 from 12; therefore there are 2 backpacks that contain only black and blue pens. 18 contain both a blue pen and a pencil. subtract 10 from 18 and you get 8. 15 contained both a black pen and a blue pen. You would subtract 10 from 15 and you get 5. There are 23 with black pens. So you would do 23 - (5+10+2)= 6. There are 6 backpacks that contain only black pens. There are 27 that contain blue pens. So you would do 27 - (5+10+8) = 4. There are 4 backpacks that contain only blue pens. There are 21 backpacks that contain a pencil. You would do 21 - (2+10+8) = 1. All together, there a 6 that contain only black pens, 5 that contain only black and blue pens, 4 that contain only blue pens, 10 that contain all three items, 2 that contain only black pens and pencils, 8 that contains only blue pens and pencils, and 1 that contains only 1 pencil. So you would add 6+5+4+10+8+2+1= 36. There are 38 backpacks, so you would subtract 36 from 38. There are 2 backpacks that contain none of the three writing instruments.
Ashfords quiz says this is right.

To write the number 403,034.66 in words, you would start by writing "Four hundred and three thousand." Then, you would add "and" before writing "thirty-four." Finally, you would write "point six six" to represent the decimal and fractional parts. So, in words, it would be "Four hundred and three thousand and thirty-four point six six."
15.73 on word form is 'Fifteen point seven three'. NB You correspondent writing 'fifteen and seventy three hundredths. is correct. However, it could still be read as as fraction '73/100'. However it is incorrect to say or write , 'Fifteen point seventy three'. Becasue the '7' in in the teneths column and the '3' in the hundredths column; it is NOT a numerical unit.
Ah, writing numbers in word form can be like painting a happy little tree. To write 0.53 in word form, you simply say "zero point fifty-three." Just like that, you've turned numbers into words, creating a beautiful picture with your language.
Oh, dude, writing numbers in word form? That's like so old school. But hey, if you really wanna know, 312,000 is written as "three hundred twelve thousand." So, like, there you go, all fancy and written out for you.
