Can some one figure what P's value is and show all steps?

Question

A = P (1+i over 100)t is up like a power

A= $628

t= 10 years

i=8%

Answer 1

a = p * (1 + i / 100)^t

p = a / (1 + i / 100)^t

p = $628 / (1 + 8 / 100)^10

p = $628 / 1,08^10

p = $628 / 2,16

p = $290,74 (initial amount)

Answer 2

this is a problem of compound interest

A = P(1+ i)^t

P = A/ (1+ i)^t

= 628/(1+ .08)^10

= 626/(1.08)^10

= 628/2.158225

=290.88
