Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years. $ Submit

Respuesta :

Given:

The initial balance = P = $74,430

Interest rate per year = r = 10% = 0.1

The interest is not compounded, so it is a simple interset

Time = t = 1 year

So,

[tex]I=P\cdot r\cdot t=74430\cdot0.1\cdot1=7443[/tex]

So, the answer is I = $7,443
