Question about advanced variances

Hi,

I have a question about the correction of an exercise if you could help me thank you 🙂

We saw in class these formulas for the material variances:

SQSP This two ones for the usage with SQ: standard quantity, SP: std price…
AQSP
AQAP This two ones for the price

so for the planning which is between the standard and the revised:

SQSP
RevisedStandardQuantitySP (RSQSP)
RevisedStandardQuantityRevisedStandardPrice (RSQRSP)

And for the operational:

RSQRSP
AQRSP
AQAP with AQ: actual quantity and AP: actual price

So my question is: I do not understand in the correction why:

For the planning variance about the PRICE: they do not use the RSQ (RevisedStandardQuantity) instead of the AQ (actual quantity) which would do 8kg*1,400u=11,200kg and not 11,000

For the operational variance about the USAGE: they do not use the RSP (RevisedStandardPrice) instead of the SP (standard price) which is $3.80 and not $4.

Thank you very much
