Kathryn and Gaby are enrolled in a university program to study abroad in
Spain and then in South Africa. They realize that they will have to convert
US dollars (USD) to euros (EUR) in Spain, and then convert EUR into
South African rand (ZAR) for their time in South Africa. They identified a
currency exchange service in Spain that will convert D dollars to euros with
the function E(D) = 0.64D -
5 and a currency exchange service in South
Africa that will convert E euros to rand using R(E) = 12.1E - 10.
Item 2: If Kathryn converts 450 USD in Spain to EUR, then converts that amount in EUR to ZAR, how much will she have in South Africa rand?
Question: Explain how to compose the functions E and R to answer item 2. Write the composite function and identify the domain and range.
