marusya05 [52]

Answer:

$184, assuming attendance of one course (not class).

Step-by-step explanation:

Total cost for one year (x) = $100 + ($7/ month)x, where x is the number of months.  

As there are 12 months in one year:

Total cost (12) = $100 + ($7/monthly)(12) = $184

<h3>How to understand power properties</h3>

Herein we must explain some properties of power expressions with integer exponents. A power of the form aᵇ is a product of the form a × a ×  a × a × ... × a, where a is repeated b times. a and b are the base and the exponent of the power.

First, we proceed to demonstrate that a⁰ = a:

a⁰            Given

a¹ ⁻ ¹        Existence of the additive inverse / Modulative property

a¹ · a⁻¹     Multiplication of powers of equal base

a¹ · (a¹)⁻¹   Power of a power / (- a) · b = - a · b

1               Existence of multiplicative inverse / Modulative property / Result

By definition of power, we find that a¹ as a is only only time.
