Answer 1

Hello!

First, let's write some important information contained in the exercise:

• Cost per hour:, $x

,

• Fee:, $2

So, we can write the expression as:

f(x) = x +2

Now, let's solve your exercise:

Which expressions represent the cost, in dollars, for 4 people to go horseback riding for 3 hours each?

So, first, we will multiply the cost per hour by 3. Then, add the fee of $2.

To finish, we will multiply the equation by 4 (number of people).

Look:

`4\cdot(3x+2)`

Possible Answers:

4 * (3x +2) or also 12x +8
