ANSWER:

a. trial plan

b. basic plan

c. 20 + 8n

d. 12n

STEP-BY-STEP EXPLANATION:

a.

We calculate the price in each case, like this:

[tex]\begin{gathered} p_b=20+8\cdot4=52 \\ p_t=12\cdot4=48 \end{gathered}[/tex]

Therefore, if you go 4 times a month, the trial plan is better.

b.

We calculate the price in each case, like this:

[tex]\begin{gathered} p_b=20+8\cdot8=84 \\ p_t=12\cdot8=96 \end{gathered}[/tex]

Therefore, if you go 8 times a month, the basic plan is better.

c.

Let n be the number of times you go per month, the cost expression of basic plan would be:

[tex]p_b=20+8n[/tex]

d.

Let n be the number of times you go per month, the cost expression of the trial plan would be:

[tex]p_t=12n[/tex]
