Respuesta :

From the statement of the problem, we know that:

• Rex paid $20 for a membership to the pool,

,

• and pays $3.00 each time he goes to the pool.

We define the variables:

• x = times that Rex goes to the pool,

,

• y = total cost.

The total cost is given by the sum:

• $3.00 x (what Rex pays every time he goes to the pool times the number of times),

,

• $20 the cost of the membership.

So we have:

[tex]y=3x+20.[/tex]

Answer

Because none of the options is equal to the equation that we found, the correct answer is D. none of these.
