Answer:
m = 20 minutes
Explanation:
given,
The Wayside Hotel charges its guests $1 plus $0.80 per minute for long distance calls.
The Blue Sky Hotel charges its guests $2 plus $0.75 per minute for long distance calls.
let the distance be m
wayside hostel charge = $1 + 0.8 m
Blue Sky Hotel charges = $2 + 0.75 m
the length of call for which the company will charge same is
$1 + 0.8 m = $2 + 0.75 m
0.05 m = $2 - $1
0.05 m = $1
m = 20 minutes
hence, the length of call for which the charge will be same is equal to 20 minutes.
