Answer:

  • 2017 Price Index is 100
  • 2018 Price Index is 111

Explanation:

The Price Index for any given Base year is always 100. 2017 is staed to be the base year so it's price index is 100.

2018

The Student Price Index can be calculated using the formula;

SPI = \frac{cost of basket of goods in the year of interest}{Cost of the basket of goods in the base year}  * 100

= \frac{(10 * 120) + (30* 390)}{(10 * 110) + (30 * 350)} * 100

= \frac{12,900}{11,600} * 100

= 111.21

= 111

Ranchers can raise either cattle or sheep on their land. Which of the following would cause the supply of sheep to increase? a d
Dafna1 [17]

Answer:

The correct answer is: a decrease in the price of cattle.

Explanation:

Ranchers can raise either cattle or sheep on their land. They will choose the option which is most profitable. A decrease in the price of cattle will make it less profitable. So ranchers will prefer to raise more sheep.

This will cause the supply of sheep to increase. As a result, the supply curve will move to the right.

An increase in the demand for cattle will increase its price. Consequently, its supply will increase and that of sheep will decrease. An increase in the price of sheep feed will make it costly to raise sheep, so its supply will decrease.  

An increase in the price of sheep will cause its quantity supplied to increase. The supply curve will remain the same.

Alika [10]

Answer:

The correct answer to the following question will be "Formal proposal".

Explanation:

  • Usually, formal proposals become prepared for bigger projects, here as in the case the expenditure demand is high, there is a huge amount of participants as well as the plan will be extensive, so formal proposals have become an easy option because informal proposals are made for projects too.
  • Grant applications should never be posted here since they are usually sent to a grant seeking agency or entity. That is just not Rene 's goal in this.

KatRina [158]

Answer: $3,866,182.89

Explanation:

The winnings in 45 years are the future value of the $80,000 that you just won based on the return rate of 9%.

Future Value = Present Value ( 1 + return) ^ number of years

= 80,000 ( 1 + 0.09) ⁴⁵
