Step-by-step explanation:

Given:

Investment P₁ = $3670
Investment P₂ = $2040
Rate of interest r₁ = 1.9% SI
Rate of interest r₂ = 5.5% SI
Time t = 5 years

Find amount of interest in both investments:

I₁ = P₁r₁t = $3670*(1.9/100)*5 = $348.65
I₂ = P₂r₂t = $2040*(5.5/100)*5 = $561.00

As we see the online savings account earns more interest and the difference is:

$561.00 - $348.65 = $212.35 ≈ $212
