Answer:

4th option

Step-by-step explanation:

using the rule of logarithms

$log^{n}$ = nlogx

$3^{7x}$ - 8 = - 2 ( add 8 to both sides )

$3^{7x}$ = 6 ( take the log of both sides )

log $3^{7x}$ = log6

7xlog3 = log6 ( divide both sides by 7log3 )

x = $\frac{log6}{7log3}$ ≈ 0.23 ( to the nearest hundredth )

Mr. Smith's $85,000 condominium is assessed at 35% of value. The tax rate is $2.70 per $100 of value. If the tax increases $.35

wel

Answer:

$907.38

Step-by-step explanation:

We have been given that Mr. Smith's $85,000 condominium is assessed at 35% of value.

First of all, we will find 35% of $85,000 as shown below:

$\frac{35}{100}\times \$85,000$

$35\times \$850$

$\$29,750$

We are also told that the tax rate is $2.70 per $100 of value. Now we will divide $29,750 by 100 as:

$\frac{\$29,750}{\$100}=297.50$

Since the tax rate is increased by $0.35 per $100 of value, so the new tax rate will be $2.70 plus $0.35.

$\text{New tax rate}=\$3.05$

$\text{Amount of new tax}=\$3.05\times 297.50$

$\text{Amount of new tax}=\$907.375$

$\text{Amount of new tax}\approx \$907.38$

Therefore, Mr. Smith's new tax will be $907.38.
