Answer:
Kim has the highest pay rate in dollars per hour
Step-by-step explanation:
we know that
To find out the unit pay rate divide the total earning by the total time
so
Nina earns $117.60 for hours 14 of work
[tex]\frac{117.60}{14}=\$8.4\ per\ hour[/tex]
Ty earns for $148.50 hours 18 of work
[tex]\frac{148.50}{18}=\$8.25\ per\ hour[/tex]
Kim earns for $137.60 hours 16 of work
[tex]\frac{137.60}{16}=\$8.60\ per\ hour[/tex]
[tex]8.6 > 8.4 > 8.25[/tex]
therefore
Kim has the highest pay rate in dollars per hour
