(b) "Cost of living" index increase by 30.73% between 2018 and 2020.

(c) "cost of living" index increase by 45.05% between 2018 and 2020.

Explanation:

Note: See the attached excel file for the calculations of the "cost of living" index for eash of 2018, 2019, and 2020 using 2018 as the base year.

(a) by how much does a "cost of living" index increase between 2018 and 2019.

Cost of living index in 2018 = 100%

Cost of living index in 2019 = 85.68%

Increase (decrease) in cost of living index = Cost of living index in 2019 - Cost of living index in 2018 = 85.68% - 100% = (14.42%)

Therefore, "cost of living" index decrease by 14.42% between 2018 and 2019.

(b) by how much does a "cost of living" index increase between 2018 and 2020.

Cost of living index in 2018 = 100%

Cost of living index in 2020 = 130.73%

Increase (decrease) in cost of living index = Cost of living index in 2020 - Cost of living index in 2018 = 130.73% - 100% = 30.73%

Therefore, "cost of living" index increase by 30.73% between 2018 and 2020.

(c) by how much does a "cost of living" index increase between 2019 and 2020

Cost of living index in 2019 = 85.68%

Cost of living index in 2020 = 130.73%

Increase (decrease) in cost of living index = Cost of living index in 2020 - Cost of living index in 2018 = 130.73% - 85.68% = 45.05%

Therefore, "cost of living" index increase by 45.05% between 2018 and 2020.

Svet_ta [14]

Answer: Making initial development private saves the government from funding all of the research.

A grant refers to an amount of money that is financial assistance thats given by the government or an organization to an individual or firm for a specific purpose. A grant is different from a loan as it isn't meant to be paid back.

Government award grants for the development of technologies, community projects, home insulation etc.

notka56 [123]

Explanation:

The computation of the cost of the machine is given below:

For Machine A

= $10,800 + $950 + $750

= $12,500

For Machine B

= $40,000 + $3,900 + $3,500

= $23,800 + $3,000 + $4,000

= $30,800

Hence, the cost of machine for A, B and C is $12,500, $47,400 and $30,800 respectively
