A=P+Prt for P given that A=$410,r=7%,t=15yrs

Question

Use the formula to solve for the given variable

Answer 1

A = P + Prt

 

Factor out the P:

 

A = P(1 + rt)

 

Divide by (1 + rt):

 

A/(1+rt) = P

 

Plug in the given values for A, r, and t:

 

$410/(1+(0.07)(15)) = P

 

$410/(2.05) = P
