In 2005, it took 20.36 currency units to equal the value of 1 currency unit in 1917. In 1990, it took only 13.20 currency units to equal the value of 1 currency unit in 1917. The amount it takes to equal the value of 1 currency unit in 1917 can be estimated by the linear function V given by V(x) = 0.4867x + 13.7333, 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 1917. Complete parts (a) and (b) below. a) Use this function to predict the amount it will take in 2009 and in 2018 to equal the value of 1 currency unit in 1917. In 2009, it will take currency units. (Round to two decimal places as needed.)
