Answer:

27 hours

Step-by-step explanation:

So t is going to represent time. $8t is equivalent to how much she makes for t amount of time. Being she is already down $16 for the gas, we have to take that into consideration that she must earn that back. Set up:

$8t - $16 = $200

Add like terms to get:

$8t = $216

Now solve for t by dividing both sides by $8.

t = 27 hours
