the average cost in 1990 is, $12,841

Step-by-step explanation:

Given the equation :

$y = 12841(1.01)^x$          ....[1]

where y represents the he average cost of an education at a private college after 1990 and x be the time in years.

We have to find the average cost in 1990.

⇒$x = 0$

Substitute in [1] we have;

$y = 12841(1.01)^0$

Simplify:

$y =\ 12,841$

Therefore, the average cost in 1990 is, $12,841

Answer 2

The average cost in 1990 is $12,841.
