Ken has to rent a car for a week and to pay no more than $130. How far can he drive if the car rental costs $94 a week plus $0.4
Elena-2011 [213]

Answer:

So he can travel a total of 90 miles

Step-by-step explanation:

Given:

Total he has to pay = $130

Per week cost = $94

Per mile cost = $0.40

To Find:

No of miles = ?

Solution:

The total he has to pay can be found out by the equation

Total = weekly cost + Miles cost

Now here

Miles cost = total no of miles traveled * per mile cost

This is due to the reason that he is travelling miles and we have to multiply it with it per mile cost to get the total miles cost

so

Let Total miles traveled be x then

Miles cost = $ 0.40 * x

Now we have

Total = weekly cost + Miles cost

Putting in the values we get

130 = 94 + 0.40 *x

subtracting 94 from both sides

130-94 = 94 + 0.40*x - 94

36 = 0.40*x

Dividing both sides by 0.4 we get

\frac{36}{0.4}=\frac{0.4*x}{0.4}

90 miles = x

or x= 90 miles

So he can travel a total of 90 miles

% is used in a lot of programming languages as the modulo operator.

a\%b=c\iff a\equiv c\mod b

which is to say, the remainder upon dividing a by b is c.

When you divide any integer by 2, you can get either a remainder of 0 or 1. So in your example, x\%2\neq0 refers to all numbers x between 1 and 9 that are not perfectly divisible by 2. In other words, x\%2\neq0 refers to those x that are odd. (This assumes B is a subset of the integers.)
