Question

Tammy has completed 52 eliveries so far this week. She needs to make 65 eliveries for the week. What percentage of her deliveries has Tammy completed?

Answer 1

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:

$X = \frac{52*100}{65}$

X = 80%

So, Tammy has completed 80% of her deliveries
