Question

Jessica is trying to save money to set aside for emergencies. she already has $75 and she earns $9 per hour at her family job. how many hours will she need to work to earn at least $500?

Answer 1

Either 55.56 or 47.222 hours, depending on how the qyuestion is interpreted. The first answer assumes that Jessica's existing savgings of $75 is not available for emergencies.

Explanation:

The question is difficult to answer. It doesn't specify that the $75 counts agains the $500. It simply asks how many hours of work does she need to earn $500.

Jessica is paid $9/hr, so her earnings (y, in $) are described by the formula: x hours at :

y = ($9/hr)*x

If we set y = $500:

$500 = ($9/hr)*x

x = $500/($9/hr)

x = 55.56 hours.

However, if we set y = $500 - $75, the Jessica only needs to work:

$425 = ($9/hr)*x

x = $425/($9/hr)

x = 47.222 hours
