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.
