Answer :
Cost=50+70*(t)
200=50+70*(t)
150=70*(t)
t=2.14 Hours
300=50+70*(t)
250=70*(t)
t=3.57 Hours
200=50+70*(t)
150=70*(t)
t=2.14 Hours
300=50+70*(t)
250=70*(t)
t=3.57 Hours
so cost=50+75t
so 200=50+75t
subtract 50 from both sides
150=75t
divide both sides by 75
2=t
$200=2 hours
50+75t=cost
300=50+75t
subtract 50 from both sides
250=75t
divide both sides by 75
10/3=t=200 mins=3hours 20 mins=$300
so 200=50+75t
subtract 50 from both sides
150=75t
divide both sides by 75
2=t
$200=2 hours
50+75t=cost
300=50+75t
subtract 50 from both sides
250=75t
divide both sides by 75
10/3=t=200 mins=3hours 20 mins=$300
