Luciahas$40,00014%annually..4years? 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. $

$22,400.

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 14%/100 = 0.14 per year,

then, solving our equation

I = 40000 × 0.14 × 4 = 22400

I = $ 22,400.00

The simple interest accumulated

on a principal of $ 40,000.00

at a rate of 14% per year

for 4 years is $ 22,400.00.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

41*67/2=1373.5
