Relevant information for material a is as follows:
actual quantity purchased and used: 6,500 lbs.
standard quantity allowed: 6,000 lbs.
actual price: $3.80
standard price: $4.00
what was the direct material quantity variance for material a?

Direct Material Quantity Variance = $2,000 Unfavorable

Explanation:

For the provided information we have,

Actual quantity used = 6,500 lbs

Standard quantity allowed for actual production = 6,000 lbs

Actual price = $3.80

Standard price = $4.00

Direct Material Quantity Variance = (Standard Quantity - Actual Quantity) Standard Price

= (6,000 lbs - 6,500 lbs) $4.00

= - $2,000

As we can see that actual quantity used is more than the allowed standard quantity, thus, the variance is unfavorable.

Direct Material Quantity Variance = $2,000 Unfavorable

answer: nobody

explanation:

of the three mortgage options that demarco and tanya have to choose from, the balloon payment mortgage would be their best option, over adjustable payment and fixed payment plans.ultimately, the balloon payment plan would save demarco and tanya overall, in interest, would cost less monthly, and they would only have to make these payments for 8 years, opposing to 30 years for adjustable or fixed payment plans. 

overall, demarco and tanya would save $80,811 if they chose balloon payments over fixed payments, and would save $116,711 if they choose balloon payments over adjustable payments. benefits with choosing fixed payments over adjustable payments is that, in the end, the payments will still be $836.30 a month, while with adjustable payments, the initial monthly payments will be $763.38 to $1082.70 a month, ultimately leading to a more costly purchase. benefits with choosing fixed payments over balloon payments are not present. benefits in choosing adjustable payments over is that it has a lower interest rate, and starts with lower monthly payments initially. benefits in choosing adjustable payments over balloon payments include a lower interest rate, and lower initial monthly payments. benefits in choosing balloon payments over fixed payments include lower interest rates, lower overall price, lower monthly payments, takes less time to pay off, and does not require a downpayment. benefits in choosing balloon payments over adjustable payments include, lower monthly payments (when averaged), takes less time to pay off, and lower overall price.

hence, option c, balloon payments, is the best option for demarco and tanya to make this purchase, for it will save them a minimum of $80811, and a maximum of $116,711.
