Suppose that an account earns 5.9% interest and after 2 years the balance is $ 4472. find the principal that was invested. use the formula bequalspplusprt, which is used to calculate the balance in an account if simple interest is added to a principal p at an interest rate of r after t years.

The principle amount = $4000

Step-by-step explanation:

Formula:

Simple interest I = PTR/100

P - Principle amount

T - Number of years

R - Rate of interest

To find principle amount

Here , P = ?, T = 2 years, R = 5.9% and p + I = $4472

I = PTR/100

P + (P*2**5.9)/100 = 4472

P[1 + 11.8/100] = 4472

P[111.8/100] = 4472

P = (4472*100)/111.8 = 4000

Therefore the principle amount P = $4000

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
