Question

CAN SOMEONE PLEASE EXPLAIN HOW TO DO THIS PLEASE?! 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 (=0) ?
A:12,969
B12,841
C:13,122
D13,099

Answer 1

I think they want you to find y when x is 0

we start with the equation
y=12841(1.01)^x

replace the x with 0
y=12841*(1.01)^0
and simplify

remember order of operations: we do exponents first.
also remember anything to the 0 power is 1 examples: 3^0= 1 or 10^0 = 1, and so on

Answer 2

so (1.01)^0 =1?

Answer 3

@phi

Answer 4

yes 1.01 ^ 0 = 1

what is y ?

Answer 5

it's B right?because 12,841x1 =12,841

Answer 6

exactly

Answer 7

okay thank you!
