Answer:
Tammy has completed 80% of her deliveries
Step-by-step explanation:
The percentage of deliveries can be calculated using a rule of three in which we know that 65 deliveries represent the 100%, then what is the percentage for 52 deliveries. This is writing as:
65 deliveries -------------------------- 100%
52 deliveries -------------------------- X
Where X is the percentage that Tammy has completed. Solving for X we get:
[tex]X = \frac{52*100}{65}[/tex]
X = 80%
So, Tammy has completed 80% of her deliveries
