The table below shows hypothetical tuition costs at a Canadian university.

Year	Tuition
2018	$5000
2019	$5050
2020	$5100
2021	$5150
2022	$5200

TABLE 2-1

Refer to Table 2-1. Assume that 2020 is used as the base year, with the index number = 100. The value of the index number in 2018 is calculated as follows:
◦ (5100/5000) × 100 = 102.
◦ 5100/5100 = 100.
◦ 5100/5000 = 1.02.
◦ (5000/5100) × 100 = 98.
◦ 5000/5100 = 0.98.

Question 2

The table below shows hypothetical monthly cell phone plan fees for the identical service over several years.

2018	$55
2019	$50
2020	$40
2021	$35
2022	$25

TABLE 2-2

Refer to Table 2-2. Assume that 2018 is used as the base year, with the index number = 100. The value of the index number in 2021 is calculated as follows:
◦ (35/55) × 100 = 63.64.
◦ 35/55 = 0.64.
◦ (35/100) × 100 = 35.
◦ (55/35) × 100 = 157.14.
◦ 55/35 = 1.57.
