Label the 3 distinct sides of the box. I arbitrarily chose the letters a, b and c.
Use the info about areas as follows:
ab=54 in^2
ac=90 in^2
bc=60 in^2
Here you have 3 equations in 3 unknowns (a, b and c), which is enough info to use to determine a, b and c. Then the volume of the box is a*b*c.
Example: bc = 90, but c = 60/b. You could subst. 60/b for c in the 2nd and 3rd equation, which will eliminate c completely and leave you with 2 equations in 2 unknowns.
Continuing this procedure, I determined that a=9, b=6 and c=10. Thus, the volume of the box is V = 9*6*10 = 540 cubic inches (answer)

You can put the dollars on the y axis and the hours on the x axis. Whenever the hours increase by 1, move over 1 on the x axis and 7.50 up on the y axis.
The first point should be (1, $7.50).

hours, money earned
The second point then will be (2, $15.00), the third will be (3, $22.50), and so on.

Answer:
If i am reading this correctly hot chocolate only requires one cup of milk, meaning you can make up to 7 cups of hot chocolate. Please tell me if that was a mistype.
