Dylan's Bicycle Shop offers a new bicycle on sale for $259.92 after a 10% markdown. What was the cost of the bicycle to Dylan if

Olenka [21]

Part A. Markdown answer = $233.93

$259.92*0.10=$25.992 or $25.99

$259.92 - $25.99 = $233.93 cost after 10% markdown

Part B. Markup answer = $337.90

$259.92 * 0.30= $77.976 of $77.98

$259.92 + $77.98 = $337.90 cost after 30% markup

(1/27)^x-6=27 Could I please have a step by step as well? Much appreciated!

Answer:

$x = 7$

Step-by-step explanation:

1) Use Division Distributive Property: (x/y)^a = x^a/y^a.

$\frac{1}{ {27}^{x - 8} } = 27$

2) Multiply both sides by 27^x - 8.

$1 = {27} \times 27^{1 + x - 8}$

3) Use the product rule: x^a x^b = x^a+b.

$1 = {27}^{1 + x - 8}$

4) Simplify 1 + x - 8 to x - 7.

$1 = {27}^{x - 7}$

5) Use Definition of Common Logarithm: b^a = x if and only if logb (x) = a.

$log_{27}1 = x - 7$

6) Use Change of Base Rule.

$\frac{ log_1 }{ log{27} } = x - 7$

7) Use rule of 1: log 1 = 0.

$\frac{0}{ log_{27}} = x - 7$

8) Simplify 0/log_27 to 0.

$0 = x - 7$

9) Add 7 to both sides.

$7 = x$

10) Switch sides.

$x = 7$

Therefor, the answer is x = 7.
