5. Car rental company A charges $30 a days and $0.15 per mile driven. Company B charges $20 a day
and $0.20 per mile driven. How many miles the
renter has to drive before the cost of the car rental
the same? What is the total cost of rental to drive
that many miles?

Step-by-step explanation:

Let the renter drives 'x' miles

Company A:

Rental cost = 30 + 0.15x

Company B:

Rental cost = 20 + 0.20x

Given rental cost are same

20  + 0.20x = 30 + 0.15x

Subtract 20 from both sides

20 + 0.20x - 20 = 30 + 0.15x - 20

    0.20x = 10 + 0.15x

Subtract 0.15x from both sides

0.20x - 0.15x = 10 + 0.15x - 0.15x

  0.05x = 10

Divide both sides by 0.05

0.05x/0.05=10/0.05

x = 1000/5

x = 200

a) The renter has to drive 200 miles

b) Rental cost charged by company A = 30 +0.15*200

                                                                = 30 + 30

                                                               = $ 60

Rental cost charged by company B = 20 + 0.20**200

                                                          = 20 + 40

                                                          = $ 60

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
