Question

Sonya is working two summer jobs, making $x per hour at the pet store, and $y per hour babysitting. Last week, Sonya worked a total of z hours and earned a total of $w. What is the value of x, y, z, and w?

Answer 1

To find the values of x, y, z, and w, we need more information or specific values for a and b.

Step-by-step explanation:

Let x = the number of hours Sonya worked at the pet store.
Let y = the number of hours Sonya babysitted.
Since Sonya worked a total of z hours, we can write the equation x + y = z.
Let's say Sonya made $a per hour at the pet store and $b per hour babysitting.
Then, Sonya earned a total of $w, so we can write the equation a * x + b * y = w.

Therefore, we have the following system of equations:
x + y = z
a * x + b * y = w

To find the values of x, y, z, and w, we need more information or specific values for a and b.
