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
420= .14p
p= 420/.14
p=3000
so p would probably be $3000
To solve the formula I=prt for p, we need to isolate the variable p on one side of the equation.
Here are the steps to solve for p:
Step 1: Start with the formula I=prt.
Step 2: Divide both sides of the equation by rt.
This gives us: I/(rt) = p.
So, the formula for p is: p = I/(rt).
Now, let's use this formula to find p when r=0.035, t=4, and I=$420.
For part B, we substitute the given values into the formula:
p = I/(rt)
p = 420/(0.035 * 4)
p = 420/0.14
p = 3000
Therefore, when r=0.035, t=4, and I=$420, the value of p is $3000.
Finally, in the answer to part B, the value of p represents the principal amount on which the interest is calculated. In other words, it is the initial amount of money that is invested or borrowed.
