Question

The equation, y = 12841(1.01)x , represents the average cost of an education at a private college, after 1990. What is the average cost in 1990 (x = 0)? (Points : 1)
$12,969
$12,841
$13,122
$13,099

Answer 1

\[y = 12841(1.01)^x \] is my guess. replace x by zero and get
\[y=12841\] because
a) any number to the power of zero is one
b) that is where you start counting from (says beginning in 1990)
