Bike is rented for $9/hour and scooter can be rented for $10/hour. So for the bike it would be 9b (9xb) and the scooter is 10s (10xs) for the total cost of both of them the answer is 9b+10s
MA=80,5-35
MA=45,5
MN/MA=MP/MB
80,5/45,5=96,6/x
80,5x=45,5*96,6
80,5x=4395,3
x=4395,3/80,5
x=54,6m
0.46666666666666. its a repeating decimal. or you could write it as 0.47.
