K pretty much i thought i had everything aced and ready, but then i found out about a whole other section of stuff i don;t know. for example this question which counts for most fo the grade on the test:
"Timber increases in value (appreciates) by 2% each year. If a consignment of timber is currently worth $100 000:
a). Express the value of the timber, P dollars, as a function of time, t, where t is the number of years from now.
b). What will be the value of timber in 10 years?
....can someone explain wtf? this all means?
