months, how much money should she save every week in order to afford the supplies she needs?

Answer 1

$15.25

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 =
`(142)/(60) > 2 =3`

Number of baskets required to store balls of yam =
`(61)/(20) > 3 =4`

Number of paint racks required to store bottles of paint =
`(35)/(81) < 1 = 1`

Total money required for the storage =
`3* 14.99 +4* 15+1* 49=\$153.97`

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 =
`(121.97)/(8)\approx \bold{\$15.25}`
