Drupady [299]

Answer:

$234

Step-by-step explanation:

First we need to define profits. Profits are Income minus Expenses:

P = I - E

We know profits are $414, so:

414 = I - E

We also can calculate income, as it is equal to price by the sales:

I = p*Q

Here she sold 90 kgs at $7.20 b kg. So:

I = p*Q = 7.20 * 90 = 648

So, replacing in profits equation:

414 = I - E

414 = 648 - E

If we sum E in both sides:

414 + E = 648 - E + E = 648

414 + E = 648

Now, subtracting 414 in both sides:

414 + E - 414 = 648 - 414

E = 234

So, her expenses are $234

Prove that if a is a natural number, then there exist two unequal natural numbers k and l for which ak−al is divisible by 10.

EastWind [94]

Assume a is not divisible by 10. (otherwise the problem is trivial).
Define R(m) to be the remainder of a^m when divided by 10. 
R can take on one of 9 possible values, namely, 1,2,...,9. 
Now, consider R(1),R(2),......R(10). At least 2 of them must have the sames value (by the Pigeonhole Principle), say R(i) = R(j) ( j>i ) 
Then, a^j - a^i is divisible by 10.
