A is the answer to the question.
Sorry for the delay!
Let x = charge before tax in 1st city, and y = charge before tax in 2nd city
y = $1500 + x
4/100x => tax in first city
3.5/100y => tax in second city
0.04x + 0.035y = $408.75
We have the following system of equations to solve:
So the hotel charge before tax in city 1 = $4750, and the hotel charge before tax in city 2 = $6250
The question is asking 'how many different ways can we pair two diplomats to shake hand'?
The combination formula is given by:
We have n = 25 and r = 2
Substituting into the formula we have
handshakes
Rational because it has an ending and doesn't go on forever. Irrational numbers do.
