Hi,

A man intends to invest $1,000 at simple interest. 

Solve the formula A = p + prt for t  t+=+%28A+-+P%29%2FPr

find how long it will take to double his money(A = 2P), at the rates of 5%, 7%, and 10%.

t+=+%282P-P%29%2FPr+=+1%2Fr+=++1%2F.05 

t+=+%282P-P%29%2FPr+=+1%2Fr+=+1%2F.07

t+=+%282P-P%29%2FPr+=+1%2Fr+=++1%2F.10
