$150 per night
Use a system of equations using x (cost of hotel) and y (cost of car):
5x + 6y = 1170
7x + 8y = 1610
Solve for y in one of the equations and then use substitution to solve for x in the other:
6y = 1170 - 5x
y = (-5/6)x + 195
7x + 8((-5/6)x + 195) = 1610
7x + (-20/3)x + 1560 = 1610
(1/3)x +1560 = 1610
(1/3)x = 50
x = $150 a night
