Step-by-step explanation:

Given:

Last week Stacy earned $24 for baby sitting for hours in her part time job at Burger city she work 12 hours and earned $78.

Now, to find the total hours she work last week.

As, given she work 12 hours and earned $78.

So, to solve by using unitary method:

If she earned $78 in working 12 hours.

So, she earned $1 in working = $\frac{12}{78}\ hour.$

Thus, she earned $24 in working = $\frac{12}{78} \times 24$

                                                        $=\frac{288}{78}$

                                                        $=3\frac{54}{78}\ hours.$
