Ok my math assignments look something ike this...
The formula I=prt gives the amouunt of simple interest I earned by principal p at an annual interest rate r over t years. Solve this formula for p.
B. Find p if r=0.035, t=4, and I=$420.
c. Writing.. That does the value p mean in your answer to part B
its simple just plug r,t and i
the it would be:-
i = ptr
420 = p*4*0.035
so p would probably be $3000
