Question

Samantha makes 18.50 an hour as a librarian. Her assistant makes 2/5 less per hour than Samantha. If her assistant works 40 hours per week, what is the assistant’s salary

Answer 1

To calculate the assistant's hourly wage, subtract 2/5 of Samantha's wage ($18.50) from her wage, resulting in $11.10 per hour. The assistant's weekly salary, working 40 hours per week, is $444.

Step-by-step explanation:

The question asks us to calculate the hourly wage of Samantha's assistant who makes 2/5 less per hour than Samantha does, and then to determine the assistant's weekly salary. Samantha makes $18.50 an hour. To find the assistant's hourly wage, we subtract 2/5 of Samantha's wage from Samantha's wage:

2/5 of Samantha's wage is (2/5) × $18.50 = $7.40.

Thus, the assistant's hourly wage is $18.50 - $7.40 = $11.10 an hour.

If the assistant works 40 hours per week, their weekly salary is 40 hours × $11.10/hour = $444.

Answer 2

The answer is $444.
First, multiply 18.50 by 0.4 you get 7.40
Then, subtract 18.50 by 7.40 you get 11.10
Finally, multiply 11.10 by 40 you get 444
