If the principal P = $500, the interest I = $250, and the rate r = 10%, find the following.

(a) What is the time?
1 years

(b) What is the future value?
$ 2

I = Po*r*t = $250.

500*0.1t = 250.
S0lve for t

b. V = Po + I = 500 + 250 = $750.

To find the time, we can use the formula:

I = P * r * t

where I represents the interest, P represents the principal, r represents the interest rate, and t represents the time.

In this case, we have:

P = $500
I = $250
r = 10% (0.10)

Substituting these values into the formula, we have:

$250 = $500 * 0.10 * t

To find t, we can divide both sides of the equation by $500 * 0.10:

t = $250 / ($500 * 0.10)

t = $250 / $50

t = 5

Therefore, the time is 5 years.

To find the future value, we can use the formula:

FV = P + I

where FV represents the future value, P represents the principal, and I represents the interest.

In this case, we have:

P = $500
I = $250

Substituting these values into the formula, we have:

FV = $500 + $250

FV = $750

Therefore, the future value is $750.
