Answer:
6 hours
Step-by-step explanation:
She already has $55, so we can subtract that from $395.
395-55 = 340
So now we can figure out how many hours she needs to work. We'll set up the problem like this, where x = the number of hours needed:
60x = 340
Divide each side by 60: x = 5.666(repeating decimal)
Rounding up to the nearest hour, Marie needs to work 6 hours.
