Step-by-step explanation:
Step one:
given
A submarine is 105 feet below the surface of the water
depth of submarine= 105 feet
let the time of ascending be x
Required
The time taken to ascend up to 81 ft
Step two:
the expression for the situation is
<em>81=105-3x</em>
solve for x
3x=105-81
3x=24
divide both sides by 3
x= 24/3
x=8 minutes

Answer:
a) difference of charges is 15 -0.05m
b) Justin should rent from EnvoCar
Step-by-step explanation:
a) EnvoCar charges ...
c = 65 +0.10m . . . . . c = charge for m miles
FreedomRide charges ...
c = 80 +0.05m
Then FreedomRide charges more by ...
(80 +0.05m) -(65 +0.10m) = 15 -0.05m
__
b) If Justin's round-trip distance is 250 miles, the extra charge from FreedomRide is ...
15 -0.05(250) = 2.50
For that distance, EnvoCar costs less. Justin should rent from EnvoCar.
_____
<em>Additional comment</em>
The additional charge from FreedomRide is zero when m=300. Above that mileage, FreedomRide charges less.
