The difference between the amounts of interest Henry and Ingrid paid for their loans is $330.

Given that,

Henry took out a 4-year loan for $5,000 and paid 4.2% annual simple interest.

And Ingrid took out a 6-year loan for $5,000 and paid 3.9% annual simple interest.

We have to find,

The difference between the amounts of interest Henry and Ingrid paid for their loans.

According to the question,

Henry took out a 4-year loan for $5,000 and paid 4.2% annual simple interest.

Then,

$Amount \ of\ interest = Principal \times rate \times time$

Where, Principal = $5000, rate = 4.2% = 0.042, and time = 4 years

Therefore,

$Amount \ of\ interest = Principal \times rate \times time\\\\Amount \ of\ interest = 5000 \times 0.042 \times 4\\\\Amount \ of\ interest = $840$

The amount of interest of Henry is $840.

Ingrid took out a 6-year loan for $5,000 and paid 3.9% annual simple interest.

Where, Principal = $5000, rate = 3.9% = 0.039, and time = 6 years

Then,

$Amount \ of\ interest = Principal \times rate \times time\\\\Amount \ of\ interest = 5000 \times 0.039 \times 6\\\\Amount \ of\ interest = $1170$

The amount of interest of Ingrid is $1170.

Therefore,

The difference between the amounts of interest Henry and Ingrid paid for their loans.

= $1170 - $840 = $330

Hence, The difference between the amounts of interest Henry and Ingrid paid for their loans is $330.
