Question

find the principal (P) if I=$1260,R=4.5%, T=7 years please help

Answer 1

i = prt
you want to find "p" or Principal, just solve for "P"
then plug in the values given

Answer 2

well... .keep in mind that 4.5% is has to be entered in decimals one sec

Answer 3

\(\bf i={\color{brown}{ p}}rt\\
i=interest\to 1,260\\
r=rate\to 4.5\%\to \frac{4.5}{l00}\to 0.045\\
t=years\to 7
\\ \quad \\
i={\color{brown}{ p}}rt\implies 1,260={\color{brown}{ p}}\cdot 0.045t\)

solve for "p" to find the Principal amount, or original deposit

Answer 4

hmm kinda missed the years there... so anyhow \(\bf i={\color{brown}{ p}}rt\\
i=interest\to 1,260\\
r=rate\to 4.5\%\to \frac{4.5}{l00}\to 0.045\\
t=years\to 7
\\ \quad \\
i={\color{brown}{ p}}rt\implies 1,260={\color{brown}{ p}}\cdot 0.045\cdot 7\)
