Answer:
3 percent which is $30
Explanation:
The real value of money is measured against a basket of goods or services, or against a particular product or service. The real value is adjusted for inflation. In other words, the real value of money is its nominal value adjusted for inflation.
If the bank pays an interest rate of 4 percent, which leads to an increase of savings from $1000 to $1040, should prices increase by 1 percent, then the real value of money has increased by 3 percent. One percent increase in prices represents inflation. Keeping $1000 in the bank will earn a 3 percent real value or $30.
Let
x = minutes used for jogging
y = minutes used for handball
z = minutes used for cycling
Th total time spent is 1 hour (60 minutes), therefore
x + y + z = 60
Because Mike jogs as long as he cycles, therefore
x = z
Therefore
2x + y = 60
or
y = 60 - 2x (1)
Jogging consumes 10 calories/min, handball consumes 9 calories/min and cycling consumes 12 calories/min.
The calories consumed in 60 minutes is 580, therefore
10 x + 9y + 12z = 580
Because x = z,
22x + 9y = 580 (2)
Substitute (1) into (2).
22x + 9(60 - 2x) = 580
22x + 540 - 18x = 580
4x = 40
x = 10
y = 60 - 2x = 40
z = x = 10
Answer:
10 minutes of jogging
40 minutes of handball
10 minutes of cycling.
Answer:
B) in the short run, an unexpected change in the price of an important resource can change the cost to firms.
Explanation:
The short run aggregate supply (SRAS) curve is upward sloping because as the price of goods and services increases, the quantity supplied will increase. In the short run, wages are more sticky than prices, and businesses can adjust prices more rapidly than employees can get a raise. This will result in businesses increasing their profit margins as the general level of prices increases, therefore the SRAS curve will be upward sloping.
An unexpected change in the price of a key input will shift the entire SRAS curve either to the right (price of key input decreases) or to the left (price of key input increases).
Answer:
Decrease by $1
Explanation:
Given:
Old data:
Q0 = 2,000 units
P0 = $20
Total revenue before change = 2,000 x $20 = $40,000
After change in Price.
Q1 = 2,100 units
P1 = $19
Total revenue After change = 2,100 x $19 = $39,900
Computation of Marginal Revenue:
Marginal Revenue = (P1 - P0) / (Q1 - Q0)
= ($39,900 - $40,000) / (2,100 - 2,000)
= -100 / 100
= $(-1)
Marginal revenue will decrease by $1
