Answer:

x = 19

Step-by-step explanation:

Assuming all angle measures are in degrees, the sum of them is 180:

(3x +16) +(4x -15) +(2x +8) = 180

9x +9 = 180 . . . . collect terms

x + 1 = 20 . . . . . . divide by 9

x = 19 . . . . . . . . . .subtract 1

The value of x is 19.

For 3 days....

option 1 : 25(3) + 0.10m = 75 + 0.10m
option 2 : 60(3) = 180

180 < 75 + 0.10m
180 - 75 < 0.10m
105 < 0.10m
105 / 0.10 < m
1050 < m.....this is minutes, we need hrs
1050/60 < m
17.5 < m.......the guest would have to spend more then 17.5 hrs
