STEP-BY-STEP EXPLANATION
Given information:
A deposit of at least $5000 will attract an annual interest of 20%
If Henry decided to deposit $5000, then he will receive the following interest
[tex]\begin{gathered} \text{amount = interest rate }\times\text{ amount deposited} \\ \end{gathered}[/tex]Interest rate =20%
Amount deposited = $5000
[tex]\begin{gathered} \text{Amount = 20\% }\times\text{ 5000} \\ \text{Amount = }\frac{20}{100}\times5000 \\ \text{Amount = }\frac{100000}{100} \\ \text{Amount = \$1000} \end{gathered}[/tex]Hence, the interest he will receive is $1000
