Question 350467
a) 


From 10:00 am to 6:00 pm, 8 hours have elapsed (2 hrs to get to 12, then 6 more to get to 6 pm)



So...


Rate of pay = Amount of money paid/number of hours = {{{120/8=15}}} dollars an hour.



b)



Since she "typed from the end of page 8 to the end of page 50", this means that she has typed 50-8 = 42 pages in total. 



So...


Average typing rate (in pages per hour) = Number of pages typed/Number of hours = {{{42/8=21/4=5.25}}} pages per hour.



c) 


Rate of pay (in dollars per page) = Amount of money paid/number of pages typed = {{{120/42=20/7=2.857}}} (this is approximate) dollars per page
