Explanation / Answer

The tables used will RAW MATERIAL, USES and PRODUCT.
The first join between RAW MATERIAL and USES gives the material with corresponding quantity.
the next join between USES and PRODUCT gives the corresponding Products and applying filter on Product Description = 'cherry end table' gives us the desired result.
Finally apply descending order on Material Standard Cost

Select RW.[Material Id], RW.[Material Name], RW.[Material Standard Cost],
US.[Goes Into Quantity]
FROM [RAW MATERIAL] RW
INNER JOIN
[USES] US
ON RW.[Material ID] = US.[Material ID]
INNER JOIN [PRODUCT] PR
ON PR.[Product ID] = US.[Product ID]
AND PR.[Product Description] = 'cherry end table’
ORDER BY RW.[Material Standard Cost] DESC
