$$28$

Given: simple interest on $$800$ at $3.5%$ in a year.

Simple Interest: $I = p r t$ , where $p = "investment amount"$ , $r = "interest rate" = %/100$ , $t = "time in years"$

For the given: $I = 800 * 3.5/100 * 1 = $28$

$color(magenta)(I = 8 * 3.5 = $28.00$

$"Simple interest " I =( P N R )/ 100$

$P = $800.00, N = 1 " year", R = 3.5$

$Interest = I = (cancel(800)^color(red)(8) * 1 * 3.5) / cancel(100)$

$color(magenta)(I = 8 * 3.5 = $28.00$
