11

James makes 7.00 

Priya makes 20% more than James = 

.2 * 7 = 1.40 

since more gonna add: 7.00+1.40= 8.40 

Priya makes 8.40 an hour

Siobhan makes 5% less than Priya=

.05*8.40 = .42 

since its less we subtract: 8.40-0.42=7.98

Siobhan makes? 

= $7.98 

12. 

45$= meal  

20%= tip  

.2*45=9$+45=54$

54$ with meal plus tip. 

6% = tax 

0.06*54=3.24 

3.24+54=57.24 

Amount of meal after tip and tax = $57.24
