Final answer:
To save an additional $2,000 in 16 months, Brianne needs to work approximately 16 extra hours per month, given her hourly wage of $8.
Step-by-step explanation:
Brianne wants to save an additional $2,000 in the next 16 months. Assuming she makes $8 an hour, we can calculate how many extra hours a month she needs to work. First, divide the total amount she wants to save by the number of months she has to save it:
Total amount to save: $2,000
Number of months: 16
$2,000 / 16 months = $125 per month
Then, calculate the number of hours needed by dividing the monthly savings goal by her hourly wage:
Monthly savings goal: $125
Hourly wage: $8/hour
$125 / $8/hour = 15.625 hours per month
As she cannot work a fraction of an hour, Brianne will need to work 16 extra hours per month.
