Rosa treated her sister to lunch while visiting her in Rockport. Their lunch costs $100, and the sales tax in Rockport is 11%. If Rosa left a 15% tip on the $100, how much in total did she pay?

pls be quick and answer this

She paid a total of $126. I hope this helps. :)

Jamie drove 2.5 hours and Raul drove 1.5 hours.  We know they traveled a total of 240 miles.  So rate x time = distance.

Jamie's distance = 2.5R (R being the speed she drove)
Raul's distance = 1.5R (R being the speed he drove)
R is the same for both since they drove the same speed.  The only thing different is time.

2.5R + 1.5R = 240
4R = 240
R = 240/4
R= 60
