Answer: $16.5/hour
Step-by-step explanation:
The unit rate is the relationship between y and x if x = 1
660/40 = 16.5
That means, if x = 1, y = 16.5
Therefore, <u>$16.5/hour</u>

Company C services 16 office suites.
Company A services 1/3 of the suites and Company B services 2/5; together they service 1/3+2/5. Find a common denominator; 15 is the smallest:
1/3=5/15
2/5=6/15
5/15+6/15 = 11/15
This means that 1-11/15 = 4/15 of the suites are serviced by Company C.
4/15 of 60 = 4/15(60) = 4/15(60/1) = 240/15 = 16
