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 % = [tex]\frac{sale price - cost }{cost}*100[/tex] \
= [tex]\frac{150}{200}*100[/tex] = 75%
3) Jada's sister commission is 3.5% of $7000
= [tex]\frac{3.5}{100}* 7000[/tex]
= $245
