Zolol [24]

Subtract the sale price from the original price then divide the difference by the original price.

Guitar 1: 160 -100 = 60

60/160 = 0.375 x 100 = 37.5%

Guitar 2: 250 - 150 = 100

100/250 = 0.4 x 100 = 40%

The answer is the second guitar has a greater percent change of approximately 40%

Answer:

$8^7$

Step-by-step explanation:

$\dfrac{8^{15}}{8^7 \cdot 8} =$

Remember that $8 = 8^1$ .

$= \dfrac{8^{15}}{8^7 \cdot 8^1}$

When you multiply powers with the same base, add the exponents. Do this in the denominator.

$= \dfrac{8^{15}}{8^{7+1}}$

$= \dfrac{8^{15}}{8^{8}}$

When you divide powers with the same base, subtract the exponents.

$= 8^{15-8}$

$= 8^7$
