mart [117]

Answer:

5 nights

Step-by-step explanation:

Solve the inequality:

90x + 90(0.1)x + 12x + 30 \leq 600

Add like terms:

102x + 30 + 90(0.1)x \leq 600

Isolate the variables:

102x + 90(0.1)x \leq 570

102x + 9x \leq 570

111x \leq 570

x \leq 5.13

So, the Lincolns can stay for 5 nights without exceeding $600
