Answer:
C) The per unit rate of people in each row = 8
Step-by-step explanation:
UNIT RATE: unit rate is defined as the rate per one unit.
Now, here, the unit rate = 8
A.)Lisa lost 8 lbs in 8 weeks.
So, the loss per week = [tex]\frac{\textrm{Amount of Loss}}{\textrm{Number of weeks}} = \frac{8}{8}[/tex]
= 1 ⇒ Per Unit Loss = 1 lbs
B.) You drove 400 mi in 8 hrs.
So,the distance covered per hour = [tex]\frac{\textrm{Total distance covered}}{\textrm{Number of hours}} = \frac{400}{8}[/tex]
= 50 ⇒ Per hour travel = 50 miles
C.)80 people in 10 rows at the movies
So,the number of people per row = [tex]\frac{\textrm{Total number of people}}{\textrm{Number of rows}} = \frac{80}{10}[/tex]
= 10 ⇒ Number of people per row = 8 people
D.)There are 100 shirts in 8 drawers
So,the number of shirts per drawer = [tex]\frac{\textrm{Total number of shirts}}{\textrm{Number of drawers}} = \frac{100}{8}[/tex]
= 12.5 ⇒ Number of shirts per drawer = 12. 5 shirts
Hence, the per unit rate of people in each row = 8
