Answer 3

?????? 15 articles have to cost more than 9 cents....

Answer 4

its 19

Answer 5

ok

Answer 6

let the no of 5 cent articles = x
then no of 8 cent articles = (15-x) ---- becoz total no of articles is 15

cost of x no of articles of cost 5 cent each = 5*x = 5x cents
cost of (15 - x) articles of cost 8 cent each = 8*(15 - x) = (120 - 8x) cents
ATQ 5x + (120 - 8x) = 19
5x - 8x = 19 - 120
-3x = -101
x = -101/-3 ??????

Pls recheck your entire question as with given figures it can't be solved.....
pls check ALL numbers/figures and revert...

Answer 7

oh okay thats abit confusin

Answer 8

total spent should be 90 cents i guess, so that the answer is:
5a+8b=90
a+b=15
a&b are the numbers of articles respectively
a=10, b=5

Answer 9

Harkirat's method is right. He is right that the figures supplied are wrong. Maybe what xwang has suggested might be the right figure.
