Answer:

Step-by-step explanation:

using the rule of logarithms

$log_{b}$ x = n ⇒ x = $b^{n}$

$log_{8}$ (x + 9) + 3 = 3 ( subtract 3 from both sides )

$log_{8}$ (x + 9) = 0 , then

x + 9 = $8^{0}$ = 1 ( subtract 9 from both sides )

x = - 8

For Judy's birthday, her friend gave her a gift card. She went to the clothing store and bought a total of $178.25 worth of clot

vladimir1956 [14]

Answer:

<h3>The percentage is 60% of the total amount paid with the gift card. </h3>

Step-by-step explanation:

Given:

Total worth of clothing is $178.25 and the amount paid with cash is $71.30.

Let us find the part of amount paid with the gift card:

Amount of gift card(G) = Total worth(T) - Amount paid in cash(C).

$G\ =\ 178.25-71.30$

$G\ =\ 106.95$ .

So, the amount paid with the gift card is $106.95.

Now, according to question:

$\frac{106.95}{178.25}\times100$

$=0.6\times100$

$=60$ %.

Therefore, the percentage is 60% of the total amount paid with the gift card.
