you would just multiply the prime factor of 400 times 2 so it would be 2x2x2x2x2x5x5.

Since 400 times 2=800
we add another 2 to the prime factors
400=2*2*2*2*5*5
800=2*400
800=2*2*2*2*2*5*5

A certain taxi driver charges a rate of r cents per person per mile. How much money, in dollars, would it cost three people to t
Anika [276]

Answer:

It would cost ( 3xr/200) dollars  to three people to travel x miles.

Step-by-step explanation:

Here, according to the question:

The rate of the taxi fare = r cents per person per mile

The total number of people travelling = 3 friends

Each person travels x miles.

So, the total distance traveled by 3 friends

= 3  ( Distance traveled by 1 friend) = (3 x) miles

Now, as each mile costs r cents.

So, the cost of travelling (3 x) miles  = ( 3 x) (r)  cents   .... (1)

Also, 100 cents = $ 1

So,  1 cent = (1/100) dollars

⇒ r cents  = (r/100) dollars

So, the cost of travelling (3 x) miles  = ( 3xr/100) dollars  .... (2)

Now, If he gives them a 50% DISCOUNT.

Then the cost of travelling (3 x) miles  = ( 3xr/ 2 x 100) dollars  

= ( 3xr/200) dollars  

Hence,it would cost ( 3xr/200) dollars  to three people to travel x miles.

50 POINTS!!! Word problem.

Let d = # of dimes
Let q = # of quarters
45 = d + q
.1d + .25q = 8.40
Then we can use the substitution method and make it so that d = 45 - q.
Then plug in the value for d into the second equation.
.1(45-q)+.25(q)=8.40
4.5-.1q+.25q=8.40
4.5+.15q = 8.40
.15q = 3.90
q = 26
d = 45 - 26 = 19
26 quarters
19 dimes
