Jada's sister works in a furniture store.

Bingel [31]

Answer:

1) $16.35

2) 75%

3) $245

Step-by-step explanation:

1) Jada earns = $15 per hour

9% increase = 15 * 9/100 = $1.35

Increased Jada's pay = 15+1.35 = $16.35

2) Markup = selling price - cost= $350 - 200= $150

Markup % = $\frac{sale price - cost }{cost}*100$ \

= $\frac{150}{200}*100$ = 75%

3) Jada's sister commission is 3.5% of $7000

= $\frac{3.5}{100}* 7000$

= $245

Answer:

We know that 1/4 = $\sqrt[4]{x}$

So, $10^{(3/4)x}$ can be written as:

$(\sqrt[4]{10})^{3x}$
