Question

The equation below represents money spent C(x) for a Netflix monthly (x) subscription. The monthly subscription is $14.99 with a sign-up fee is $5. Determine the value given the situation above. a. C(10) = $ b. Ci ) = $94.94

Answer 1

The equation for spent on the Netflix is,

$C(x)=5+14.99x$

(a)

Substitute 10 for x in the equation to obtain the value of C(10).

$\begin{gathered} C(10)=5+14.99\cdot10 \\ =5+149.9 \\ =154.9 \end{gathered}$

So, C(10)=$154.9.

(b)

Substitute 94.94 for C(x) in the equation and simplify to obtain the value of x.

$\begin{gathered} 94.94=5+14.99x \\ 14.99x=89.84 \\ x=\frac{89.94}{14.99} \\ =6 \end{gathered}$

The value of x is 9. So C(6)=$94.94.
