2 320 is invested for two years at 14% p.a simple interest
At 12% p.a compound interest
which is a better investment and by how much

It's 14% p.a simple interest

Step-by-step explanation:

Simple interst:

I = $ 649.60

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

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

then, solving our equation

I = 2320 × 0.14 × 2 = 649.6

I = $ 649.60

The simple interest accumulated

on a principal of $ 2,320.00

at a rate of 14% per year

for 2 years is $ 649.60.

Compound interest

A = $2,945.78

A = P + I where

P (principal) = $2,320.00

I (interest) = $625.78

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 12/100

r = 0.12 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 2,320.00(1 + 0.12/12)(12)(2)

A = 2,320.00(1 + 0.01)(24)

A = $2,945.78

Summary:

A line of best fit can only be drawn if there is strong positive or negative correlation. The line of best fit does not have to go through the origin. The line of best fit shows the trend, but it is only approximate and any readings taken from it will be estimations.
