Well for the small box of Cornflakes you want to divide $6.30 by 18 and you should get $0.35 which is how much each oz cost.
For the large box you want to convert 2.2 lb to oz, you will get 35.2 oz. Next just do the same divide $8.80 by 35.2 and get $0.25 which is the cost for each oz in the large box.
X Times x is x^2
X^2-8x+3x-24
x^2-5x-24
X is the number
x/5=5a+4
2 digits that are odd
sum is 10
ah, we can make a bit of stuff with the last 2 hints
sum is 10 and are odd
that is
9 and 1
3 and 7
5 and 5
so our possible numbers are
91,19,37,73,55
but 55 is divsible by 5 so it is out
91,19,37,73
test each
91/5 has remainder 1
19/5 has remainder 4
37/5 has remainder 2
73/5 has remainder 3
the number is 19
