Fish eggs
Step-by-step explanation:
Answer:she spent 10 hours working in her aunt's store last week.
Step-by-step explanation:
Let x represent the number of hours that Lee spent working at the movie theater.
Let y represent the number of hours that Lee spent working at her aunt's store.
Lee worked a total of 30 hours at the movie theater and her aunt's store. This means that
x + y = 30
Her combined pay from the jobs was $240. She earned $9 per hour working at the movie theater and $6 per hour working in her aunt's store. This means that
9x + 6y = 240 - - - - - - - - - -1
Substituting x = 30 - y into equation 1, it becomes
9(30 - y) + 6y = 240
270 - 9y + 6y = 240
- 9y + 6y = 240 - 270
- 3y = - 30
y = - 30/ - 3 = 10 hours
Given:
Number of pen you are to purchase = 240 pens
Number of staplers you are to purchase = 6 staplers
Cost of pen in sets = 6 for $2.35
Cost of stapler in sets = 2 for $12.95
Let's find how much it will cost to purchase these products.
First find the average cost of each item:
![\begin{gathered} \text{Average cost of pen = }\frac{2.35}{6} \\ \\ \text{Average cost of stapler = }\frac{12.95}{2} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctext%7BAverage%20cost%20of%20pen%20%3D%20%7D%5Cfrac%7B2.35%7D%7B6%7D%20%5C%5C%20%20%5C%5C%20%5Ctext%7BAverage%20cost%20of%20stapler%20%3D%20%7D%5Cfrac%7B12.95%7D%7B2%7D%20%5Cend%7Bgathered%7D)
To find the total cost, we have the equation:
Total cost = (Average cost of pen x number of pens to be purchased) + (Avg cost of stapler x number of staplers to be purchased)
![\text{Total cost = (}\frac{2.35}{6}\times240)+(\frac{12.95}{2}\times6)](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20cost%20%3D%20%28%7D%5Cfrac%7B2.35%7D%7B6%7D%5Ctimes240%29%2B%28%5Cfrac%7B12.95%7D%7B2%7D%5Ctimes6%29)
Let's evaluate the equation:
![\begin{gathered} \text{Total cost = (}\frac{2.35\times240}{6})+(\frac{12.95\times6}{2}) \\ \\ \text{Total cost = (}\frac{564}{6})+(\frac{77.7}{2}) \\ \\ \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctext%7BTotal%20cost%20%3D%20%28%7D%5Cfrac%7B2.35%5Ctimes240%7D%7B6%7D%29%2B%28%5Cfrac%7B12.95%5Ctimes6%7D%7B2%7D%29%20%5C%5C%20%20%5C%5C%20%5Ctext%7BTotal%20cost%20%3D%20%28%7D%5Cfrac%7B564%7D%7B6%7D%29%2B%28%5Cfrac%7B77.7%7D%7B2%7D%29%20%5C%5C%20%20%5C%5C%20%20%5Cend%7Bgathered%7D)
Solving further:
![\begin{gathered} \text{Total cost = (}94)+(38.85) \\ \\ \text{Total cost = }132.85 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctext%7BTotal%20cost%20%3D%20%28%7D94%29%2B%2838.85%29%20%5C%5C%20%20%5C%5C%20%5Ctext%7BTotal%20cost%20%3D%20%7D132.85%20%5Cend%7Bgathered%7D)
Therefore, the amount for purchasing these products will cost $132.85
