Answer:

The answer is: B) People face trade-offs

Explanation:

A trade-off happens when you have to balance two (or three in this case) opposing situations.

Rina has to decide how to divide the time she can spend training. If she chooses to do one activity, she can´t do the other. So she has to balance the time spent on each activity, probably depending on which sport she needs to train the most.

A stock sells for $6.99 on December 31, providing the seller with a 6% annual return. What was the price of the stock at the beg
Dimas [21]

Answer:

Correct option is 6.59

Explanation:

Selling price of stock at the end of the year is $6.99. Annual return rate is 6%. Price of stock at the beginning will be present value of stock valued at the end discounted at 6%. Computation is as shown below:

Present\ value\ or\ price\ of\ stock = Selling\ price\left ( \frac{1}{1+i} \right )^{n}

= 6.99\left ( \frac{1}{1+0.06} \right )^{1}

= \frac{6.99}{1.06}

= $6.59

Therefore, Stock's price in the beginning of the year is $6.59.

A country reported nominal GDP of $200 billion in 2010 and $180 billion in 2009. It also reported a GDP deflator of 125 in 2010
QveST [7]

Answer:

19%

Explanation:

Given that,

Nominal GDP in 2010 = $200 billion

Nominal GDP in 2009 = $180 billion

GDP deflator in 2010 = 125

GDP deflator in 2009 = 105

Percentage change in prices:

= Percentage change in GDP deflator

= (Change in GDP deflator ÷ GDP deflator in 2009) × 100

= [(125 - 105) ÷ 105] × 100

= (20 ÷ 105) × 100

= 0.19 × 100

= 19%

Therefore, the prices increases by 19%.

Given that

Sales = $979,000

Variable manufacturing expense = $232,000

Variable selling and administrative expense = $110,650

The computation of contribution margin ratio is shown below:-

Contribution margin ratio = (Sales - Variable manufacturing expense - Variable selling and administrative expense) × 100 ÷ Sales

= ($979,000 - $232,000 - $110,650) × 100 ÷ $979,000

= ($979,000 - $342,650) × 100 ÷ $979,000

= $636,350 × 100 ÷ $979,000

= 65%
