Boof<br>$543.51 is subtotal.
antiseptic1488 [7]

Answer:

The total of the sales price and sales tax is  $ 588.35 .

Step-by-step explanation:

As given

$543.51 be the subtotal .

8.25% is the sales tax .

8.25% is written in the decimal form.

= \frac{8.25}{100}

Sales tax price = 0.0825 × 543.51

                         = $ 44.84  (Approx)

Total of sales price with sales tax = Sale price + Sales tax price

Putting the values in the above

                                                       = $543.51 + $44.84

                                                       = $ 588.35

Therefore the total of the sales price and sales tax is  $ 588.35 .

If 32^2c= 8^c+7, what is the value of c
Leona [35]

\bf 32^{2c}=8^{c+7}~~ \begin{cases} 32=2\cdot 2\cdot 2\cdot 2\cdot 2\\ \qquad 2^5\\ 8=2\cdot 2\cdot 2\\ \qquad 2^3 \end{cases}\implies (2^5)^{2c}=(2^3)^{c+7} \\\\\\ 2^{5(2c)}=2^{3(c+7)}\implies \stackrel{\textit{if the bases are the same, then so are the exponents}}{5(2c)=3(c+7)\implies 10c=3c+21} \\\\\\ 7c=21\implies c=\cfrac{21}{7}\implies c=3
