A cab in NYC charges you $1.25 a mile and a flat fee of $4 to ride in the cab. A cab in Chicago charges you $0.75 a mile but a f
Vikentia [17]

Answer:

After 4 miles driven by cab the amount would be same in both cities.

Step-by-step explanation:

Let the number of miles be 'x'.

Given:

In NYC

Flat fee of cab = $4

Per mile charge = $1.25

Total cab charges is equal to sum of Flat fee of cab and per mile charge multiplied by number of miles.

Framing in equation form we get;

Total cab charges in NYC = 4+1.25x

In Chicago

Flat fee of cab = $6

Per mile charge = $0.75

Total cab charges is equal to sum of Flat fee of cab and per mile charge multiplied by number of miles.

Framing in equation form we get;

Total cab charges in Chicago = 6+0.75x

Now we need to find number of miles driven so that the amount could same in both cities.

Total cab charges in NYC = Total cab charges in Chicago

4+1.25x=6+0.75x

Combining like terms we get;

1.25x-0.75x=6-4\\\\0.5x=2

using Division Property we will divide both side by 0.5 we get;

\frac{0.5x}{0.5} =\frac{2}{0.5} \\\\x=4

Hence After 4 miles driven by cab the amount would be same in both cities.

I need the answer to this question
malfutka [58]
Hi there friend:)


Your answer would be to add because 'gain" is the clue word to adding because it means adding on to something or means to have or get more of something added on, so when you add 5 + 0.25 you get 5.25, so 5 + 0.25 =
5.25


Sorry if its wrong

Have A Happy Thanks Giving With Family and Friends

Happy Holidays ^_^
