Answer:
$15.25
Step-by-step explanation:
Given that
Sadie has 142 spools of thread,61 balls of yam and 35 bottles of paint.
Capacity and price of a rack = 60 spools of thread, $14.99
Capacity and price of a basket = 20 balls of yam, $15
Capacity and price of a paint storage rack = 81 bottles of pain, $49
Money already saved = $32
To find:
Money to be saved each week for having all the necessary storage in 2 months.
Solution:
It can be analyzed that to store 142 spools of thread,61 balls of yam and 35 bottles of paint and as per the storage capacity:
Number of racks required to store thread = ![\frac{142}{60} > 2 =3](https://tex.z-dn.net/?f=%5Cfrac%7B142%7D%7B60%7D%20%3E%202%20%3D3)
Number of baskets required to store balls of yam = ![\frac{61}{20} > 3 =4](https://tex.z-dn.net/?f=%5Cfrac%7B61%7D%7B20%7D%20%3E%203%20%3D4)
Number of paint racks required to store bottles of paint = ![\frac{35}{81} < 1 = 1](https://tex.z-dn.net/?f=%5Cfrac%7B35%7D%7B81%7D%20%3C%201%20%3D%201)
Total money required for the storage = ![3\times 14.99 +4\times 15+1\times 49=\$153.97](https://tex.z-dn.net/?f=3%5Ctimes%2014.99%20%2B4%5Ctimes%2015%2B1%5Ctimes%2049%3D%5C%24153.97)
Money already saved = $32
More Money to be saved = $153.97 - $32 = $121.97
There are 8 weeks in 2 months, so money to be saved every week = ![\frac{121.97}{8}\approx \bold{\$15.25}](https://tex.z-dn.net/?f=%5Cfrac%7B121.97%7D%7B8%7D%5Capprox%20%5Cbold%7B%5C%2415.25%7D)
