Explanation:

Step1: Calculate commission amount

Commission = $800 \times 4.5\% = 800 \times 0.045$

Step2: Calculate markup percentage

Markup % = $\frac{\text{Selling Price - Cost}}{\text{Cost}} \times 100\% = \frac{70-20}{20} \times 100\%$

Step3: Calculate new hourly wage

New wage = $15 \times (1 + 6\%) = 15 \times 1.06$

Answer:

1. $\$36$
2. $250\%$
3. $\$15.90$
