Question

In 2005, it took 18.54 currency units to equal the value of 1 currency unit in 1915. In 1990, it took only 13.30 currency units to equal the value of 1 currency unit in
1915. The amount it takes to equal the value of 1 currency unit in 1915 can be estimated by the linear function V given by V(x) = 0.3584x + 13.9132, where x is the
number of years since 1990. Thus, V(11) gives the amount it took in 2001 to equal the value of 1 currency unit in 1915. Complete parts (a) and (b) below.
a) Use this function to predict the amount it will take in 2008 and in 2017 to equal the value of 1 currency unit in 1915.
In 2008, it will take currency units.
(Round to two decimal places as needed.)

Answer 1

Answer:

2008 - 1990 = 18

x = 18

v(x) = 0.3584x + 13.9132

= 0.3584 × 18 + 13.9132

= 6.4512 + 13.9132 = 20.3644 = 20.36

in 2017

2017 - 1990 = 27

= 9.6768 + 13.9132 = 23.59
