Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

• $a^{-m}$ ⇔ $\frac{1}{a^{m} }$

• $a^{0}$ = 1

• $a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

Given

(a)

$8^{-2}$ = $\frac{1}{8^{2} }$

(b)

$\frac{1}{3^{-3} }$ = 3³

(c)

$6^{-12}$ × $6^{8}$ × $6^{0}$

= $6^{(-12+8)}$ × 1

= $6^{-4}$

= $\frac{1}{6^{4} }$

Theresa has a credit card that uses the average daily balance method. For the first 12 days of one of her billing cycles, her ba

katrin [286]

Using the average daily balance method, the amount to be used in calculating Theresa's interest is given by:

$\frac{350\times12+520\times19}{12+19} = \frac{4200+9880}{31} \\ \\ = \frac{14080}{31} =$454.19$

Therefore, the interest charge on Theresa for the biling cycle is given by:

$\frac{454.19(0.14)}{12} = \frac{63.59}{12} \\ \\ =\$5.30$
